I haven't used the machine in a long time and now that I am, I forgot many things. My needle keeps breaking, thread breaks, and my even zig zag stitch is interupted with long stitches. I'm going to try a #11 needle for the thin flannel I'm trying to sew because that's the only needle I have left. But before I did, I wanted to ck to see if I had everything else set right. Any ideas?
