I was sliding around on a sports hall floor for some training activity and my tracksuit bottoms, which are polyester Adidas clima365, but not the synthetic type, have thin, long burns on the material at the knee. The stitches have sort of split, but with holes only at the top layer of material, not all the way through. I would really appreciate it if anyone could suggest ways in which i could repair them, stop them from splitting or anything like that. They are my favorite pair so any help would be awesome!
