Oh, please be careful. I have been told that magnetic on your electronic (computerized) sewing machine is not a good idea. Mine may have quit because I had one of those pin magnets on top of it. May be put it inside the cushion, but on the outside, facing us?
Cute idea too. I have one of those magnetic one for your wrist, but I am so small, the strap is so long... Now I have an idea to modify it.
THank you for the link.
