Plastic Flowers

I have these plastic bottle flowers on the brain. It all started with the fabulous show on the Sundance Channel called Man Shops Globe. Then, I've been seeing the flowers popping up everywhere. The only problem I have is, I've cut plastic bottles out of our lives. I'm going to ask the parents to save some soda bottles for me. I think this will be a fun new craft to try out. Making trash useful. I'm going to use my flowers in a wreath. Here are a few posts I found on the subject:
