I've got 2 spools of the 140 and one spool of the 70 denier and with each one the thread has gotten buried/trapped; end up having to cut it free so now I have 2 loose ends to go along with my wit's end. Love the stuff, the 140 is my favorite thread for foam flies, and it only has happened with tan, but I use a lot of tan; I can usually get 2 or 3 flies tied before I have to untangle it again. Anyone else have this problem?
