My sewing machine and I are in a bit of a war right now. It's probably my fault - I stopped using it for a few weeks, it got lonely, it took revenge. But I've been working on some super secret Christmas projects, and I have never had this much trouble. Needle coming unthreaded, thread breaking, bobbin running out in the middle of a seam (okay, that one might be my fault), bobbin tangling, thread tangling. And then, while attempting to untangle the bobbin at one point, I accidentally pulled the bobbin case out, and it took me forever to figure out how to put it back in.
These are the slowest moving "quick" projects ever.
