Oh my gosh! I did the most fun swap a few weeks ago! It was a great exercise for my creativity, that's for sure. I was assigned a partner and we each sent an envelope full of stuff to one another. Once we got the stuff we were supposed to use it to make 2 ATCs for our partner. Well... my partner sent me a TON of stuff so I was able to make 3 ATCs for her and still had stuff left over! It was a lot of fun.
