Thread for Sewing Slipcovers


T-40 Spun Polyester, 6,000 Yard Cone

T-40 spun polyester is a strong thread for industrial straight stitch machines. I use it to sew all of my slipcovers no matter the fabric.  I keep basic colors on hand:  white, antique cream, khaki, dark grey, black and dark navy.

T-27 Spun Polyester, 6,000 Yard Cone

T-27 spun polyester thread is the one I use on my 2-needle, 4-thread industrial serger. This is a strong, quality thread that works great for overlocking seams on all types of slipcover fabrics.

This is a wholesale resource for medium-firm welt cord. It has a poly tissue-like core and wrapped with a poly braided cover. It’s firm enough to keep its shape yet soft enough to bend around curves smoothly.

Doesn’t shrink or pucker when slipcover is washed under normal conditions. The 5/32 size is standard for slipcovers. A smaller size 4/32 is also available.
