We could each make a certain size (to be determined later, I'm leaning toward 6.5") traditional block and pin it to our shirt or in my case dress, then when we run into each other we could exchange. We might exchange 20 times throughout the day. Each person that has it could add their own small label with their screen name to the back of it. It would be fun to see how many times they were exchanged. The person that made the block could put a star by their name. That way we could see who made it and each person that had it. Just an idea. We could use our own favorite colors or pick a color theme that suited everyone (yeah, right, like that could happen LOL) We could even pick a certain block like a Monkey Wrench, 9 patch, Churn Dash, or whatever, just something that would identify us to each other.
