joyerbides, just go to Home Depot and in their paint department they will have samples of Disney paint. The paint chips are in the shapes of Mickey's head! Pick up a few paint chips of the Alien Green color - these are your lime green Mickey head paint chips, aka LGMHPC's. People do different things with them - I peel mine off the backing (no need to soak or anything, if you are careful they will just peel right off) and use a labelmaker to put my DISboards screen name on them. I've also taped them to paper and printed my username on them, but the ink doesn't stay that well. I've seen people just write on them with a Sharpie, it doesn't really matter. Then I sandwich two together back-to-back and laminate them with Contac paper and trim around the edges, punch a hole in them and clip them onto whatever I want to! Sometimes I'll wear one on my lanyard, or clip it onto my diaper bag or camera case or stroller. Just something to identify myself to fellow DISers. I like to also carry extras so that if I meet a DISer, I can give them one and they will remember who they met. I've met quite a few DISers who spotted my LGMHPCs, but I can never remember who they are by the time I get home.
Somewhere there is a whole thread about the LGMHPCs and what people do with them. Have fun and maybe we'll spot each other at SSR!
