Forester Report post Posted November 20, 2016 Hi All. I bought myself a tippman boss sewing machine not long back and I love it, the only problem I have is when I try to lock off the stitching, I end up with an ugly clump of thread on the back. Has anybody else had this problem and if so what is the best way to end sewing or ways to make it look more pleasing on the back.
