Has anyone used these gloves while hand sewing? I saw them at joann's, they are green in color, say they help since they keep your hands warm and are a snug fit. I can see how they may help but since they are a little costly (much rather spend my money on fabric) I thought I would get your opinions before I purchase. Of course I have a fifty percent off coupon if I decide to buy them. Reason I want them is because sometimes while hand sewing my wrists and hands cramp, thought maybe these might help. Opinions wanted....
