Could you need a new needle? If all else fails I'd take it to a LQS or a sewing machine shop and ask for help. My machine was messing up horribly once and several ladies piped in "try a new needle". Holy crap they were right! Put in a new needle and voila...Beeeeautiful stitchin'
hey could you let us know what the issue is when you get it solved? It''ll work out.
