Sewing Thread

Choose polyester or cotton-wrapped polyester for general home decor because they balance strength and low stretch; use 100% cotton for quilts and natural fibers, silk for delicate fabrics, and heavy-duty nylon or bonded polyester for upholstery and high-stress seams

Thread weight is often shown as a number or denier; for curtains and cushions use medium-weight threads (coarse weights like 30–50wt or labeled 'all-purpose'); for upholstery and heavy-use items choose heavier or upholstery-specific threads (lower wt numbers or bonded/nylon varieties)

Small projects like cushion covers or pillow shams often require one to two spools; larger items such as curtains or slipcovers may need several spools depending on size and seam allowance—estimate by calculating seam length and adding 20–30% for topstitching and waste

Choose fade-resistant or colorfast threads for items exposed to sunlight; pick a matching color or a slightly darker shade for concealed seams and a contrasting decorative thread with a durable finish for visible topstitching; test on scrap fabric to confirm colorfastness

Store spools in a cool, dry place away from direct sunlight and dust; keep them on a horizontal rack or in sealed containers to prevent tangling and humidity damage, and avoid storing next to heat sources that can degrade synthetic fibers

Many all-purpose polyester threads work for both machine and hand sewing, but for heavy-duty hand seams or visible handwork use stronger upholstery or waxed threads; ensure the needle size and hand-sewing needle eye accommodate the thread thickness

Match thread weight to needle size—finer threads need smaller needles and heavier threads require larger needles; using too thin a needle with thick thread can fray or break the thread, while too large a needle can leave oversized holes in delicate fabrics
