I have not done anything with mine since we are planning to use them in the next few months..
However I had the idea to put them in a vase (like line them up on top of one another) and then put my antenna topper collection on little rods in them and make like a bouquet of sorts..
Mine from the list trap are customized. The friend I went with and I traded after the trip as a sort of "friendship bracelet" type gift! Right now, I have her's just hanging out in my car. No idea what I'll do with it permanently.
