Simthread polyester embroidery thread kit — 120 colours (107 solids + 13 variegated), trilobal sheen & durable

Simthread's 120-colour polyester embroidery thread kit supplies 107 solid and 13 variegated trilobal spools engineered for vivid sheen, reliable strength, and wide machine compatibility.

This kit was designed to expand your colour options beyond common manufacturer collections. It pairs high-tenacity trilobal polyester yarn with careful colour selection so hobbyists, small business embroiderers, and quilters can stitch complex palettes without frequent thread swaps. Simthread bundles conversion references and a bonus prewound bobbin thread to speed setup and match tones across brands.

What makes these polyester threads different from other kits?

Simthread uses trilobal polyester yarn, a next-generation filament that reflects light for brighter, glossier stitches than standard polyester. The 120-spool assortment combines 107 plain shades and 13 variegated tones chosen to avoid overlaps with common Brother palettes, giving you unique transitional colours.

• Trilobal poly yarn for enhanced sheen and colour depth
• 107 solids + 13 variegated spools for broader palette choices
• Colours selected to differ from Brother sets, reducing duplication
• Included conversion chart for Madeira and Robinson-Anton matching

Which machines and projects work best with this thread kit?

These polyester spools are compatible with most home and commercial embroidery machines — from Brother and Babylock to Janome, Singer, and Bernina. The thread’s strength and smooth finish reduce breakage and shredding, so it supports dense fills, monograms, appliqué, and quilting stitches.

• Safe for single-needle and multi-needle embroidery heads
• Suitable for sergers and most sewing machines using polyester thread
• Good for dense embroidery and frequent stitching without frequent stops
• Works well on apparel, linens, patches, and decorative quilting

How do I match these spools to other thread brands and set up quickly?

The kit includes a conversion colour chart to help map Simthread shades to Madeira and Robinson-Anton references, making colour planning faster. A bonus prewound bobbin thread is provided so you can start stitching right away while matching bobbin tones to top-thread colours.

• Conversion chart for Madeira and Robinson-Anton colour matching
• Prewound bobbin thread included to reduce setup time
• Clear spool labels to identify colours and numbers quickly
• Recommended needle and tension adjustments may vary by machine

How durable and colourfast are these threads in everyday use?

Manufactured from high-quality polyester, Simthread spools deliver excellent tensile strength and colour retention for regular laundering and wear. Polyester’s inherent resistance to fading and abrasion means embroidered pieces keep their brightness longer under normal use and cleaning conditions.

• High tensile strength to resist breakage and splitting
• Good colorfastness for routine washing and light exposure
• Trilobal finish maintains vividness across stitch types
• Recommended for items that require frequent handling
