Super strong!
Ordered this thread to redo the hem on some livestock curtains and was looking for something suitable for outside use. This is the strongest thread I have ever used, but very flexible and easy to work with. I started handstitching as I did not want to take a chance on my home machine, but I am going to switch to the machine now. Love, love, love this thread. I also do a bit of leatherwork and I am going to try it there also.
