I have been busting my butt making paper flowers for our centerpieces. I am getting close to finishing, and now I need to figure out how to arrange them. I am planning to put them in mason jars (I already own a ton of them) and tying a ribbon around the top. However, I am really worried about them falling over. Does anyone have any ideas about what I could use to weight them down? Whatever I use will be seen, so it has to be pretty. I thought about those colored glass pebbles, but they seem to be so expensive.
