when you pull them out of the cork board, do the hello kitties come off of the tacks?
I was worried about that, but they have stayed stuck together very well. I used this gel type super-glue, if it makes any difference. I've been twisting them out of the cork pretty carefully though, just in case.
where did you find shrinky dink paper?
Truth be told, it was in a pile of old craft supplies in my basement, I must have bought it five years ago. But I believe I originally found it at Hobby Lobby. All you do is draw on the shrinky paper, cut out the picture, and put it in the oven for a minute or two. It shrinks to about 1/3 the original size. And thanks everyone for the compliments!
