Absolutely would not allow my machine out of my house without me. Too much money invested to let someone misuse it. I would allow them to use it in my presence only. You'd be surprised how even very nice people can do little things that make big problems... My cousin who I love like a sister has a lot of trouble with her machine. I was at her house when she was sewing one day and noticed that she was running her machine pretty fast sewing over pins....That ain't gonna happen on mine. I told her that I now know why it goes to the shop fairly often. And guess what!!!!!! She still does it. Because it doesn't mess up every time doesn't mean it won't.
