This thread comes on a 4 ounce spool. How many feet is that? That is a question often asked by our customers, but we don't know exactly how many feet that is. Our closest estimate is 3,600 ft. That is plenty to last days of non-stop sewing. This thread is T92 bonded polyester, and is plenty strong at about 14.4#/stitch. We have numerous colors that are available, and add more as we can.Follow us on Twitter for links to daily specials, "Like" us on Facebook for access to a coupon code for your next order & subscribe to our Youtube Channel.
