The unmounting project is coming along nicely, though it did interfere a little with my concentration on Thanksgiving prep earlier today!! As has been suggested by several people, I followed this method of unmounting my Stampin' Up! stamps. For most of my wood mounted stamps, the red rubber peels right off the foam mount with no problem. Stampin' Up! stamps are stuck on there pretty well, though. I suppose it's a sign of quality, but when you're unmounting them it's a sign of impending frustration. I don't know yet how I feel about keeping the foam mount attached to the red rubber, but I don't suppose it will be much of a problem, and I'm doing it for now. I'm down to the last few that need to be unmounted, and then I can work on getting them all stickified with Tack It, sorted, filed, and put away!
As an added note, when I ran out of Tack It I went to Joanns to get more. Wouldn't you know, they didn't have it. So I got the Zig 2-Way glue instead, as I've heard it can be used for the same thing. While I appreciate it's application better (chisel tip pen style applicator), it just doesn't have the same "oomph" when it comes to the temporary hold. So I'll put that glue in my bag to take to crops and whatnot, but I think I'm an official Aileene's dedicatee.
