I’m a big fan of Artist Trading Cards.  I joined a trading club a few years ago and traded a few cards via snail mail.  It was really fun.  Unfortunately I stink at keeping up with most things mail related, especially thank you notes, so it sort of fizzled out.  I introduced the concept to the kids at summer camp last week and they really took to it.  We had mini trading sessions a few times, but mostly the kids wanted to keep their own.  I don’t blame them.  They did a really nice job.  We helped make them special by using some japanese washi tape I got on etsy, which basically makes everything look awesome.  This is a great center for when kids are done with the main project we’re working on.  Here are some of the kid’s ATCs.
