I just got what I think is a unique idea for a swap, inspired by one of the challenges in Top Chef. If you are a fan, you might remember when they cheftestants have done a relay quickfire in which they are broken into teams of 4, and while 3 of the team members are blindfolded, the other member prepares food with an idea in mind for what the dish should be. Then each other member in turn is given a chance to add to or modify the dish until the last person completes the composed dish. It's really interesting to see whether or not the team members get a sense for what the first person wanted to create or if they all try to add their own spin on the dish.
So my idea is for a Relay Swap. I would break up participants in teams/groups of 4, and one person would start making an item with polymer clay (it could be anything) and then send it off to the next person who can add/embellish or change the first item and then send it on to the next person, and so on. I think I would rotate who the initial person would be in each team/group, so that it isn't always the same person who has to "start" the piece. And I think it would be cool if the first person to start the piece is the one who gets to keep the finished piece in the end.
Those are my basic ideas for how the swap would work. It would require timeliness and reliability (and so I would probably only sign up people I know, considering what has happened in other swaps in the last year or so). Let me know your thoughts or if you're interested. I think it could be really interested, challenging and fun!
