Go one shade darker
When in doubt, a slightly darker thread blends into the seam, while a lighter one tends to show.
-
For prints, match the background
Choose the background or the most dominant colour, and the stitches will disappear into the print.
-
For topstitching, go bold
On visible stitching, contrast is often the point. Gold or copper on denim is a classic.
Choosing the Right Needle for Your Thread
The right thread works best with the right needle. Heavier topstitching thread needs a needle with a larger eye, knits need a ballpoint or stretch needle to avoid skipped stitches, and fine fabrics call for a sharper, smaller needle. Our guide walks you through needle types and sizes so your thread, needle and fabric work together.
FAQs About Sewing Thread at Core Fabrics
-
An all-purpose polyester thread works for almost any linen or cotton project, and organic cotton thread is a natural match if you want an all-natural garment. Recycled all-purpose thread is strong with a little give, so seams hold up to washing and wear. Organic cotton thread presses at high heat and wears in alongside the fabric, but it has very little stretch, so use polyester for high-stress seams.
-
Use a polyester all-purpose thread. Its slight stretch moves with the fabric, while cotton thread can snap when a knit seam is pulled. Pair it with a stretch or zigzag stitch on your sewing machine, or finish knit seams on a serger.
-
Yes. For everyday garment sewing, recycled polyester (rPET) thread performs like conventional polyester thread. It’s made from post-consumer plastic, such as bottles, processed back into polyester fibre, so you get the same strength, colourfastness and slight stretch with less virgin plastic.
-
All-purpose thread is for the seams that hold a garment together. Topstitching thread is heavier and made for stitching you want to see, like the double rows on jeans, jacket edges and bag straps. Use topstitching thread in the needle only, with all-purpose thread in the bobbin, and pair it with a topstitching or jeans needle and a longer stitch length.
-
Use serger thread, which comes on large cones made for the high speed of an overlocker. Most sergers use three or four threads at once, and neutral shades like white, ivory, grey, navy and black cover most projects, since serged seams are usually hidden inside the garment.
-
Thread weight describes thickness: the higher the number, the finer the thread. A 50wt thread, like our Scanfil organic cotton, is a medium-fine weight suited to garment sewing, while topstitching thread is noticeably thicker.
