I'm sorry for the machine frustrations. Tell yourself it is a learning experience AFTER you take it to the dealer. You will feel a lot better when everything is checked over. They will also be able to give you one-on-one information. It is so much harder to troubleshoot a new machine when you are new to sewing as well.
Just so you know, my first machine was a Singer Touch and Sew. We've decided it should have been renamed a Touch and Throw. My Mother-in-Law informed my husband it was enough to make a person lose their religion and to get me one that worked right. :lol: I spent years thinking it was ME when I actually had a machine that would not be timed correctly no matter who did the repair.
