Lot of vintage thread on big spools... this is from the from the estate of a saddlemaker, and is all heavy duty thread for leather work, harness repair or sewing canvas.
We think these big spools make great display pieces, too. The largest is about 6" tall x 3 3/4" in diameter.
All of this thread have been stored in a barn for years, and has some fading / soil to the exposed thread. It's all really strong thread, almost impossible or impossible to break. But we're not sure of the fiber content on this lot, sorry!
