that really was a good idea and I don't know if it's my sewing machine (a FW) or the magnet, but it doesn't have a lot of "stick" power to it. I may just put a stronger magnet on top to help hold it in place. Don't know if it will work, but gonna give it a try.
Oh yeah, I've never redone a block. Either it's good the first time or it stays the way it is, lol! I don't have the patience to take one apart and redo it. It's gonna have to be ok the way it is. I'm happy with it.
