I don't want to throw them away if I don't have to, but I'm having trouble thinking of what to do with them. the plastic is too thick for me to put christmas lights into, and I thought about using them for single flower vases (by drilling holes near the top of the point), but that doesn't seem like the best use, plus I don't usually have fresh flowers around. I'm able to take the stickers off the front and back so that it looks plain like this:

So, any ideas?
