|Just a little something I discovered while trying out this tip: if you plan to sew without thread, don't just unthread the needle and start sewing. Instead, snip and remove the thread just as you would do if you were changing thread. I just unthreaded the needle, and when I went to thread it again, there was thread all wrapped and knotted around the takeup lever. Luckily I didn't just try to yank the thread out (I knew that was a bad idea) and I was able to carefully snip the knotted threads to get them off. But if the lever had been less accessible, I would have had to take it into the shop. Ick.
