Simthread Polyester Embroidery Thread — 80-Spool Assortment, 40wt 500m Spools, Colourfast Machine Thread

Simthread Polyester Embroidery Thread is an 80-spool set of 40-weight, 500m (550yd) polyester threads in an assorted palette designed for machine embroidery projects.

This collection packs a broad selection of bright, washable colours compatible with major embroidery machines and colour charts so you can match Janome and Robinson-Anton shades. Each spool contains 500 meters of durable 100% polyester thread with consistent tension, good colorfastness and reliable performance for appliqué, monogramming, logos, quilting accents and crafted home textiles.

What makes these threads suitable for machine embroidery?

Simthread uses a 40-weight polyester that balances sheen and strength for machine use: thin enough to produce crisp detail yet strong enough to resist breakage. The threads feed smoothly through most embroidery machines and are less prone to linting than some natural fibres, reducing maintenance and skipped stitches.

• 40wt thickness for clear stitch definition and good coverage
• 500m per spool reduces changeovers during large projects
• Low-lint polyester minimizes needle clogs and machine cleaning
• Consistent twist and tension for uniform stitching

How do these threads hold up to laundering and regular wear?

Polyester resists fading and chemical exposure better than many other fibres, making these spools a practical choice for garments and linens that see frequent washing or commercial laundering. They retain colour and tensile strength through washing, bleaching and everyday abrasion so finished pieces keep a neat appearance longer.

• High colorfastness for repeated washing and commercial care
• Resistant to fading from sunlight and chlorine-based bleaches
• Elasticity reduces thread breakage and puckering on garments
• Durable tenacity suited for workwear, uniforms and linens

Which machines and projects are these threads compatible with?

These threads are engineered to work with an extensive range of home and commercial embroidery machines. Simthread supplies a conversion chart for Janome and Robinson-Anton colours so you can easily match existing projects or designs, and the assortment covers many everyday and decorative colour needs.

• Compatible with Brother, Bernina, Babylock, Janome, Husqvarna, Singer and Innov-is models
• Good for machine embroidery, appliqué, monograms, quilting accents and decorative stitching
• Colour chart and conversion references help match OEM palettes
• Assorted set reduces time spent swapping spools for multi-colour designs

How do I choose colours and manage large projects with this set?

The 80-spool assortment provides a wide spectrum from brights to neutrals so you can plan multi-colour designs without immediate restocking. Use the provided colour chart to align spools with your machine’s colour numbers, and take advantage of the 500m spool length for longer runs before replacing thread.

• Assortment includes brights, pastels, neutrals and specialty tones
• Reference Janome and Robinson-Anton conversion charts for matches
• 500m spools reduce interruptions during extended stitching
• Organize spools by project palette to speed setup and colour swaps

Who is this for? Crafters, small-business embroiderers and hobbyists who need a reliable, economical supply of polyester thread will find this 80-spool Simthread set useful. It’s especially helpful for those handling repeated laundering, uniforms, promotional items or multi-colour embroidery runs that benefit from consistent thread quality, long spool lengths and a broad palette. If you want bright, lasting colours, lower thread breakage and broad machine compatibility, this kit is built to support both everyday projects and higher-volume stitching.
