I think this would be a fun swap. I know I do a lot of smaller projects and I have to buy some stuff in bulk when I know I will only really be using it once. I would love to pass some of that stuff along to someone who could use it.
If your using Shrinky Dinks they will curl while they are shrinking and lay flat when they are done. I have also placed a brown paper bag over top of then and set a heavy book on top when they got out too, just to be safe.
You know I LOVE your monsters. LOVE them. These are fantastic. Love that scientist and the background on the red one is great too! Here are a couple random ideas for more monsters.... Due to the season you could do an Angel or an Elf, maybe even a Santa! A monster holding a cat (I am imagining it sitting on his head!) or even a dog for those poor people who do not have a cat in there lives. A hippie, one in motorcyle gear, fishing, holding a bunch of books from the library, bride and groom, or the most interesting Monster in the World (Dos Equis). A Frankenstein one (but I would beg you relentlessly for that one!). One texting on his phone (we all have one of those in our lives). Hmmm. I will think some more. Can't wait to see your next batch. It's like your raising Mogwai! LOL!
