100% Nylon Thread is strong enough to withstand the wear and tear of the everyday life that upholstrey projects undergo and last for a long, long time. Make those cushions, furniture covers, or throws to last! Each box of thread contains 4 x 137M spools. Sorry colors cannot be mixed.
Sewing Tip: Be sure to use a machine needle with a large enough eye that thread slips through easily so thread will not fray or break while you are sewing.
