I recently bought an old singer 15-91 is suppose to be ready to go but I cant get it to sew! When u thread it is it suppose to be tight? The thread does not pull easily like my other machine! 2. Do they have to be in a case or cabinet to run? It moves all over when Im trying to sew. I only got it to make 1 stitch! What am I doing wrong? I just got it Wed and only have 7 days to return! It didnt have a manual so we downloaded one in parts online. Has 100 pgs!
Thanks!
