Has anybody use wine corks for place card holders? I'm wondering how you get them to stand up. I know you lay them down horizontally and then put a slit in them to place the place cards, but it seems that they would lean back and fall down. Any suggestions?? I ordered business cards through vistaprint and am using them as the place cards. Just trying to find an inexpensive way to have them on the table without having to lay them down. Any suggestions?? Don't have to be cork related.
