Don't you hate it when other things get in the way of quilting and fondling your fabric, hahaha. I was hopeful that the bobbin case that came with the 301 would fit one of my machines. Possibly this 15 clone. Miriam suggested I check out the site Tools for self Reliance and it is a good one. My bobbin area is not quite the same as any of the ones shown, but close to the last one. So I may need more than just the hook and bobbin case. A tension C/Y clip?? I'm off the next 2 days and will go through all my machines to see what I have and if any are close to the clone's bobbin area.
