Unfortunately, this is less of a tip and more of an unavoidable truth.
Sewing machines freeze, they crash, they seize up and do things that you have not asked for. And they can make you as frustrated and annoyed as any poorly behaved computer.
In explaining this fact to me, my mother achieved little other than my continued avoidance of sewing machines. The last time I used one, several years ago, I broke three needles in one sitting.
