Simthread All-Purpose Polyester Thread 20-Colour 366 m Spools with 16 Needles — 30wt Corespun, Machine & Hand Sewing

Simthread All Purpose Thread is a 30-weight corespun polyester set of 20 colour-matched 400-yard spools designed for hand sewing, quilting, piecing, and general machine repairs.

Whether you sew every day or mend occasionally, the right thread makes every stitch stronger and more consistent. Simthread’s all-purpose polyester collection is made from high-grade raw materials used by leading brands, offering colorfastness, dependable stitchability and enough yardage to tackle multiple projects. Each set includes 20 carefully selected shades and 16 needles, making it a practical kit for patching, quilting, garment construction and everyday household sewing.

How durable is Simthread for machine sewing and handwork?

Simthread uses corespun polyester at a 30-weight thickness that balances strength and visibility, so seams hold up to daily use without being overly bulky. The polyester composition resists stretching and fading, while the corespun finish smooths feeding through machines and reduces breakage when hand sewing.

• 400 yards per spool: long length reduces frequent spool changes.
• 30-weight corespun: sturdy yet fine for most fabrics.
• High colorfastness: resists running and fading in normal laundering.
• Machine- and hand-friendly: suitable for standard home sewing machines and hand needles.

Which projects is this thread best suited for?

This thread is intended as a true all-purpose option: from piecing quilt blocks to repairing seams and hemming garments. It performs well on woven and many knit fabrics, making it a convenient go-to for hobbyists and makers who work across different fabric types.

• Quilting and piecing: consistent stitch formation and colour selection for blocks.
• Everyday sewing: hems, seams, and alterations on shirts, dresses and pants.
• Repair and mending: reliable strength for patches and reinforcement stitches.
• Crafts and decorative work: smooth finish for visible topstitching and trims.

How do I choose the right colour and use the included needles?

To blend thread into fabric, place the spool next to the material and select the shade that appears to disappear against the textile. The kit’s 16 hand needles and the range of 20 colours make simple mends or on-the-spot repairs straightforward without buying extra tools.

• Colour matching tip: hold thread against fabric in natural light to find the least visible match.
• Needle assortment: includes general-purpose hand needles suitable for regular mending tasks.
• Combo purchases: recommended to pair with white and black spools for maximum versatility.
• Works on various fibres: polyester thread complements cotton, wool and synthetic blends.

Will this thread work with specialty fabrics and delicate seams?

While formulated to be versatile, this all-purpose polyester performs best on everyday and medium-weight fabrics. For very delicate silks or heavy upholstery, you may prefer a thread specifically developed for those specialties; however, Simthread remains a reliable option for most household sewing and quilting tasks.

• Everyday fabrics: ideal for cotton, blends and midweight synthetics.
• Delicate fabrics: test on a scrap; use finer threads if needed for sheer silks.
• Heavy-duty needs: consider heavier weight threads for upholstery or leather.
• Pre-test recommended: stitch a quick sample before finishing visible seams.

Who is this for? Simthread All Purpose Polyester Thread is tailored for hobby sewers, quilt makers, independent designers and home sewists who want a dependable, economical thread collection. If you value consistent stitch quality, a wide palette of colours and the convenience of included hand needles, this set is a practical addition to any sewing kit. It’s especially useful for crafters who switch between machine work and hand mending and those who prefer to keep a well-rounded colour selection on hand for quick repairs and ongoing projects.
