Does anyone have any ideas for keeping your punches from sticking? I've never had this problem before but I ordered one off Ebay (so it would be a little more time consuming to just return it) and it keeps sticking. The more I work it, the looser it gets but when I actually punch paper it still gets stuck. My seller said to try waxpaper but with this punch I have NO IDEA how you could do that. (it's the swirl head Mickey punch) Any tips?
