Just another hint, make sure your rubberbands are pretty good quality... I have bought several packages at Dollar Tree, and Dollar general and they weren't worth my time. They were very poor quality and break easily. The best one's I've found has been from Sally's.. You can also find them at Walmart and the brand Goody is good quality, but you don't get very many in a pack and I think they are a little expensive, They don't have very good stretch either but they break even less than the one's from sally's.
Hope it works well for you.
