This was a project my Mom did and it is so easy and cheap. You can do it with different colors to match any room or theme. You just need a glass vase and glass gems (like you might put in the bottom of a fish tank). I have seen them at Wal-mart, the dollar store, and Michael's, so I think they are pretty easy and cheap to find. Then you just hot glue them on. You can start around the base and just go up, or try and create cool patterns. Put some flowers in and you are good to go!
