For the sake of experimentation I just went in my sewing room and made
one with 2 SOS pads, rolled in batting then covered the whole thing with
muslin. Nothing fancy. The pins do get sharper but I don't think I'll leave my
pins in there. You have to work the pins back and forth a few times or
should I say several times if they are really dull but it does work. A lot of
work to sharpen a pin. LOL
Maybe I'll try emery next. The little tomato is completely useless. Don't
waste your money on that one. I read that they don't even have emery in
them now. Pfft.
