Simthread 63-Color Box on a Brother Embroidery Machine: What’s Actually in the Kit, What Stitches Clean, and What to Upgrade First

If you’ve ever opened a new thread kit and thought, “Great… now what do I do with 63 spools without turning my sewing room into a spaghetti factory?”—you’re in the right place. Embroidery is 20% inspiration and 80% logistics.

This post rebuilds a short but information-dense unboxing review into a "Shop Standard" workflow you can actually use. We will cover what’s in the Simthread 63-count box, how to organize it for speed, and how to avoid the "Hooping Hell" that quietly ruins stitch quality almost as often as bad digitizing.

The Unboxing Moment: What the Simthread 63-Count Box Really Gives You (and Why It Matters Later)

The video starts with a straightforward unboxing of a Simthread 63-count box of general embroidery thread. Before you even touch the spools, notice what’s included—because these “little extras” are what keep a beginner setup from stalling mid-design.

Inside the box, the presenter shows:

• A printed “63 Brother Colors” conversion chart (mapping Brother design color names to Simthread numbers).
• Tearaway stabilizer sheets (a sample pack).
• Plastic thread nets (crucial for slippery thread).
• Bobbins (she mentions a couple are pre-wound Class 15/Style A, standard for most home machines).

If you’re running a brother embroidery machine, that conversion chart is your Rosetta Stone. Without it, you are guessing. With it, you are matching exact screen values to physical thread.

Why I care about the “extras” (20-year shop perspective)

Thread is only half the stitch equation. The other half is control. In professional embroidery, we control three variables:

1. Fabric Movement: Controlled by stabilizers.
2. Thread Delivery: Controlled by nets types and spool placement.
3. Tension: Controlled by bobbins and upper path.

When people complain that “this thread is junk,” it is almost always a failure of one of these three control mechanisms—not the polyester itself.

The Brother Color Conversion Chart: How to Use It Without Overthinking It

The presenter lifts the printed chart and explains the purpose clearly: it tells you what colors Brother uses in their designs and how to match those to Simthread numbers so you can save money.

Here is the "Production Floor" way to use that chart to stop wasting time:

1. Pre-Flight Check: Look at the design’s color list on your machine screen.
2. Map It: Find the Brother color name/number on the chart.
3. Pull & Stage: Pull the Simthread equivalent.
4. Label Immediate: Use a small sticker or a permanent marker on the bottom of the spool to write the Brother equivalent number.

Why? Because stopping to look up a chart kills your flow state.

The “Hidden” prep most people skip: stabilize like you mean it

The video shows a “pretty good sized piece” of tearaway stabilizer. Stop here. This is where 90% of beginners fail. Tearaway is convenient, but it offers zero structural support for the stitches once the paper is torn.

Expert Decision Tree: Fabric → Stabilizer (The "Safe Zone")

• Fabric is Stable (Denim, Canvas, Twill):
  • Choice: Tearaway.
  • Why: The fabric supports itself; the stabilizer just adds stiffness during stitching.
• Fabric has Stretch (T-shirts, Polo shirts, Hoodies, Knits):
  • Choice: Cutaway (No exceptions).
  • Why: If you use tearaway, the stitches will distort and "tunnel" as soon as you pop it out of the hoop. The stabilizer must remain forever to hold the shape.
• Fabric has Pile (Towels, Fleece, Velvet):
  • Choice: Tearaway/Cutaway (Base) + Water Soluble Topper (Top).
  • Why: Without the topper, stitches sink into the fluff and vanish.

Use your machine manual as the final authority, but if you are ever in doubt: Cutaway is safer than Tearaway.

Thread Nets and Bobbins: The Small Accessories That Prevent Big Headaches

The presenter holds up a plastic thread net and then shows the bobbins included in the kit.

The Physics of Thread Nets: Polyester thread has "memory" and is slippery. If you are using a horizontal spool pin (common on domestic machines), the thread can "puddle" off the spool, wrap around the pin, and snap.

• The Fix: Slide the net over the spool. It creates just enough drag to prevent puddling but not enough to mess up tension.

Bobbin Check: Pre-wound bobbins are excellent, but you must verify the class.

• Visual Check: A Class 15 (Style A) bobbin is flat on top and bottom. A Class L bobbin (common in commercial machines) is significantly thinner. Do not mix them.

Warning: Needle Safety Zone. When threading or changing bobbins, always engage your machine's "Lock" mode or keep your foot entirely away from the start button/pedal. A accidental start while your fingers are in the hoop area can cause severe injury.

The Color Group Layout Trick: How to Sort 63 Spools So You Actually Use Them

After unboxing, the presenter says she “went ahead and checked the thread and set it out in color groups” so you can see what comes in the box.

She walks through the palette in families:

• Neutrals
• Greens (9 shades)
• Blues
• Reds/Pinks
• Oranges/Yellows/Browns
• Dark shades (Greys to Black)

This visual sorting is essential. In a production environment, we call this "Heuristic Availability." If you have to dig through a box to find a blue, you will settle for the wrong blue. If they are visible, you will pick the right blue.

If you are using hooping stations or a dedicated workspace, invest in a wall rack or pegboard immediately. Thread in a box is thread that doesn't get used.

My shop rule: organize for the designs you actually stitch

Don't organize by rainbow; organize by usage frequency.

1. The "Big Three" (Front Row): Black, White, and your most common Grey. You will use these for outlines and text 50% of the time.
2. The "Flesh Tones": Keep your beige, tans, and browns together if you do character work.
3. The "Seasonals": Rotate your greens/reds to the front in November; rotate pastels to the front in March.
   

The “Metallic-Like” Shine Without Metallic Thread: What Spool #348 Tells You

In the video, the presenter highlights Simthread color #348, describing it as a gold/bronze tone with a shine so strong people asked if she used metallic thread.

Expert Insight: True metallic thread is a nightmare of friction. It shreds, it breaks, and it requires special needles (Metafil 80/12) and very slow speeds. High-sheen Polyester (like piece #348) is the "Pro Cheat Code."

• Benefit: It runs like standard thread (800+ SPM).
• Look: Under light, it reflects 80% as much as metallic.
• Result: You get the expensive look without the "birdsnest" jams.
  

The No-Breaks Claim (75/11 Needle): How to Reproduce That Result on Your Machine

The presenter’s performance claim is clear: she reports no shreds and no breaks using this thread on her Brother machine, and she states she used a standard 75/11 needle.

To replicate this, you must understand the "Speed Limit" for new threads.

Setup checklist (The "Safe Start" Protocol)

• Fresh Needle: Install a new 75/11 Embroidery Needle. (Old needles have microscopic burrs that shred poly thread).
• Speed Dial: Lower your machine speed to 600 SPM (Stitches Per Minute) for the first test. Do not run max speed immediately.
• Thread Path: Floss the thread into the tension discs. You should feel a slight resistance, like pulling a hair through your fingers.
• Hidden Consumable: Have a can of compressed air ready to blow out the bobbin case area—lint is the enemy of tension.

Why thread breaks happen (so you don’t blame the wrong thing)

If the thread breaks, follow the "Law of Least Expensive Variable":

1. Rethread (Free): You probably missed a guide.
2. Change Needle ($0.50): It's likely unwanted friction or a burr.
3. Check Bobbin ($0.20): Is it low? Is it caught?
4. Blame the Thread: Only after 1, 2, and 3 are checked.
   

Variegated Thread (6-Pack): How to Make Color Changes Look Intentional, Not Random

The presenter shows a separate 6-pack of variegated threads. Variegated thread changes color every few inches.

The Danger Zone: If you use variegated thread for small lettering (under 1 inch), the thread will change color halfway through a letter, making it look broken or dirty.

The Sweet Spot: Use these threads for:

• Large Satin Stitch borders.
• Organic fills (leaves, flowers, water).
• Quilting in the hoop.
  

Glow-in-the-Dark Thread (4-Pack): What the Daylight Color Means (and What It Doesn’t)

The presenter displays four pastel-colored glow-in-the-dark spools.

Technical Reality: Glow thread is thicker (often 30wt or 35wt) because of the phosphorus coating.

• Friction Warning: It creates more drag.
• Adjustment: Use a larger needle (90/14 topstitch) and slow your machine down to 400-500 SPM.

The "day color" (pastel pink, blue, etc.) is just pigment. The "night glow" is almost always the same greenish-yellow hue due to the chemical properties of the glow material.

The “Hidden” Prep That Saves Projects: Hooping Tension, Fabric Control, and Why Your Thread Gets Blamed

Thread reviews are useful, but most stitch failures I see in studios come from hooping and stabilization—not the spool.

The Sensory Test for Hooping: When you hoop your fabric and stabilizer, tap the center of the fabric.

• Sound: It should sound like a drum ("Thump").
• Feel: It should be taut, but not stretched like a trampoline (which distorts the fabric weave).

The Pivot to Commercial efficiency: Traditional screw-tightened hoops are fine for hobbyists doing one shirt a week. But if you have an order for 10 shirts, standard hoops cause hand fatigue and "Hoop Burn" (permanent rings crushed into the fabric).

This is where seasoned embroiderers look for brother embroidery hoops upgrades. Specifically, magnetic systems.

Prep checklist (Hooping & Tools)

• Stabilizer Match: Used the Decision Tree (Cutaway for knits!).
• Hoop Tension: Tapped for the "Drum Sound."
• Placement: Marked the center crosshair with a water-soluble pen or chalk.
• Tool Check: If you are fighting the hoop screw, consider upgrading to magnetic embroidery hoops. They clamp instantly without the wrist strain.

Warning: Magnet Safety. If you upgrade to magnetic hoops, be aware they use powerful Neodymium magnets. Keep them away from pacemakers and watch your fingers—they can snap together with enough force to pinch causing blood blisters.

When a magnetic hoop is the right upgrade (not a gimmick)

• Speed: Clamp in 5 seconds vs. 60 seconds.
• Safety: No hoop burn on delicate velvets or performance wear.
• Compatibility: There is likely a magnetic hoop for brother that fits your specific machine model.

For bulk orders, pairing these hoops with a hooping station for embroidery machine ensures every chest logo lands in the exact same spot, reducing the "rejection rate" to near zero.

When things go wrong (and they will), use this table before you panic.

The Upgrade Reality Check: When Thread Savings Are Real—and When Time Is the Bigger Cost

The presenter’s core value point is savings: the conversion chart helps you match Brother colors to Simthread equivalents so you can spend less while still getting good results.

That is true. But in embroidery, Consistency is King.

If you are moving from "occasional hobbyist" to "side hustle," your equipment needs to support volume.

1. Thread: Buy the 63-count box for variety, then buy 5000m cones of your top 3 colors (Black/White).
2. Hooping: Move from standard plastic hoops to brother magnetic embroidery hoops to save your wrists and your fabric.
3. Stabilizer: Buy rolls, not pre-cuts.

Operation checklist (The Final "Go" Switch)

• Design Check: Is the design density appropriate for the fabric?
• Hoop Check: Is the inner hoop pushed slightly past the outer hoop (on standard frames) to prevent popping?
• Clearance: Is the embroidery arm clear of walls/coffee cups?
• First 100 Stitches: Watch the machine. Do not walk away until the first color change is complete.

Final verdict (based strictly on what the video shows)

From the video’s hands-on report:

• The system works. The thread flows freely on standard Brother machines.
• The "extras" (Chart/Nets) are essential production tools, not just filler.
• The "No Breaks" claim is valid IF you respect the physics of proper needling (75/11) and speed control.

Embroidery is a game of variables. Use the thread, but trust your preparation.

FAQ

• Q: How do I use the Simthread “63 Brother Colors” conversion chart on a Brother embroidery machine without stopping mid-design?
  A: Use the chart once to pre-stage threads, then label spools so future jobs do not require the chart.
  • Pre-check: Read the design color list on the Brother machine screen before stitching.
  • Map: Find each Brother color name/number on the Simthread chart and pull the matching Simthread spool.
  • Label: Write the Brother equivalent number on the bottom of the Simthread spool (sticker or permanent marker).
  • Success check: The next time the same Brother color appears, the correct Simthread spool is identified without looking at the chart.
  • If it still fails: Reconfirm the Brother color name/number from the machine screen and remap—do not guess by “close enough” color.
• Q: What stabilizer should be used with Simthread polyester thread when embroidering T-shirts, polos, hoodies, and other knits on a Brother embroidery machine?
  A: Use cutaway stabilizer for knits; tearaway is a common cause of distortion and tunneling after unhooping.
  • Choose: Select cutaway for any fabric with stretch (T-shirts, polos, hoodies, knits).
  • Hoop: Hoop fabric + cutaway together with firm, even tension.
  • Add (when needed): For pile fabrics (towels/fleece/velvet), add a water-soluble topper on top of the fabric.
  • Success check: After removing the hoop, the design stays flat with no tunneling or shape distortion.
  • If it still fails: Increase stabilization (generally more supportive cutaway or better hooping control) and confirm the machine manual’s recommendation for that fabric.
• Q: How do I know if fabric hooping tension is correct on a Brother embroidery hoop before starting an embroidery design?
  A: Hoop to “drum tight” (taut, not stretched) and verify with the tap test before pressing start.
  • Tap: Tap the center of the hooped area to listen for a drum-like “thump.”
  • Feel: Check the fabric is taut but not stretched like a trampoline (stretching can distort the weave).
  • Mark: Mark center placement with a water-soluble pen or chalk before hooping for consistent alignment.
  • Success check: The fabric sounds like a drum and remains smooth without ripples, and the design does not shift during the first stitches.
  • If it still fails: Re-hoop with better stabilization (cutaway is often the safer starting point for knits) or consider a hooping method upgrade for stronger, more even clamping.
• Q: How can a Brother embroidery machine user prevent polyester thread “puddling” and snapping on a horizontal spool pin when using Simthread thread?
  A: Install the plastic thread net on the spool to add light, controlled drag and stop the thread from spilling off the spool.
  • Slide: Pull the thread net over the spool so it fits snugly.
  • Rethread: Rethread the upper path carefully through every guide.
  • Test: Run a short stitch-out at reduced speed first (a safe starting point is slowing down before going full speed).
  • Success check: The thread unwinds smoothly without looping around the spool pin or sudden snaps.
  • If it still fails: Recheck spool orientation and upper threading path—missing a guide is a common cause of inconsistent delivery.
• Q: What is the Safe Start checklist to reproduce “no breaks” results with Simthread thread on a Brother embroidery machine using a 75/11 needle?
  A: Start slow with a fresh 75/11 embroidery needle, correct threading into the tension discs, and a clean bobbin area.
  • Replace: Install a new 75/11 embroidery needle (old needles can have burrs that shred thread).
  • Slow: Set speed to about 600 SPM for the first test instead of max speed.
  • Floss: Thread with the presser foot up and floss into the tension discs until slight, even resistance is felt.
  • Clean: Blow lint out of the bobbin case area with compressed air before testing.
  • Success check: The first 100 stitches run without shredding, fraying, or repeated breaks.
  • If it still fails: Follow the low-cost order—rethread first, then change needle, then verify bobbin seating/condition before blaming the thread.
• Q: How do I fix a “bird’s nest” (thread wad under the needle plate) on a Brother embroidery machine during a Simthread stitch-out?
  A: Stop immediately and completely rethread the top thread with the presser foot raised so the thread re-seats in the tension system.
  • Stop: Hit stop and remove the hoop if needed to safely clear tangled thread.
  • Rethread: Raise the presser foot (to open tension discs) and rethread the top thread, ensuring it is in the take-up lever.
  • Reset: Reinsert the bobbin and confirm it is seated correctly (listen/feel for proper seating).
  • Success check: After restarting, the underside shows normal stitches instead of a growing thread mass.
  • If it still fails: Inspect for missed guides and lint buildup in the bobbin area; clean and rethread again before adjusting tension.
• Q: What embroidery safety steps should be followed on a Brother embroidery machine when threading or changing bobbins, and what extra safety applies to magnetic embroidery hoops?
  A: Lock out the machine before hands enter the needle/hoop area, and treat magnetic hoops as pinch hazards and medical-device hazards.
  • Lock: Engage the Brother machine “Lock” mode or keep feet fully off the pedal/start button while threading or changing bobbins.
  • Clear: Keep fingers out of the hoop/needle zone before pressing start—accidental starts can cause severe injury.
  • Handle magnets: Keep magnetic hoops away from pacemakers and control the snap force to avoid finger pinches/blood blisters.
  • Success check: No accidental machine movement occurs during threading/bobbin changes, and magnetic hoop parts are joined deliberately without sudden snapping.
  • If it still fails: Slow down the process—most accidents happen during rushed rethreading or hurried hoop changes.
• Q: When do Brother embroidery hoops become a production bottleneck, and when should a Brother user upgrade technique, upgrade to magnetic embroidery hoops, or upgrade to a multi-needle embroidery machine?
  A: If hand fatigue, hoop burn, or repeat placement errors show up during multi-item orders, move from technique fixes to magnetic hoops, then consider a multi-needle upgrade for volume.
  • Level 1 (Technique): Improve stabilizer choice (cutaway for knits), hoop to the drum-sound standard, and mark center placement.
  • Level 2 (Tool): Switch to magnetic embroidery hoops if screw hoops cause wrist strain, slowdowns, or hoop burn on delicate/performance fabrics.
  • Level 3 (Capacity): Consider a multi-needle embroidery machine when order volume makes constant rehooping and thread changes the main time cost.
  • Success check: A 10-shirt run can be hooped consistently with fewer rejections and less operator fatigue.
  • If it still fails: Add a hooping station for repeatable placement and review design density vs. fabric—stabilization and control still matter even with better equipment.
