I'm having a problem with the stitch on my Bernina 1130. It's not forming a tight stitch. The top stitch goes along and looks ok, then it will start to look flat. See photo... the bottom is the loopy side. Any ideas? I've cleaned the machine, used a new needle, new bobbin, same good quality thread on top and bottom. I've thought about oiling the machine, but haven't done it yet. I can't do the 70 mile roundtrip, or the 100.00 repair cost right now and I'm certain it's something simple. I'm sure hoping that someone here can help figure it out so I can get my projects done!
