Polyester Upholstery Thread 300 m - CHARCOAL

Polyester Upholstery Thread in Charcoal is an extremely strong and durable sewing thread designed for heavy-duty stitching and upholstery work.
Made from 100% polyester, this thread offers excellent abrasion resistance while remaining soft and flexible for neat, flat seams.
Ideal for sewing leather, vinyl-coated fabrics, denim, canvas, and carpet materials, this thread provides reliable seam strength where durability is essential.
The deep charcoal shade is a versatile dark neutral, perfect for modern upholstery fabrics and projects where a subtle, professional finish is required.
With a practical 300 metre spool, this thread is well suited to upholstery projects, bag making, furniture repairs, and other heavy fabric applications.
Thread Weight Explained
This thread is 40wt, meaning it is thicker and stronger than standard all-purpose sewing thread.
A 40wt thread is ideal because:
- It provides strong seams for heavy fabrics
- It resists abrasion and wear
- It creates firm, secure stitching
- It remains flexible for flat, neat seams
- It is suitable for upholstery and repair work
Lower weight number = thicker thread
Higher weight number = finer thread
40wt is a popular choice for upholstery and heavy-duty sewing.
