I have been trying to figure out how to make flowers out of plastic bottles for weeks now. I have cut them up, melted them, put them in the oven and had no success until I started looking at the bottoms of the bottles which are already kind of star shaped, So I cut one from a 2 liter soda bottle apart and cut each little section into a pointy petal. To create the leaf, I just cut a leaf shape out of a peice of the rest of the bottle that was already curled slightly. For the small pink flower I did the same with a water bottle and then flipped the bottle over and pushed the petals out. I think they are adorable. A little paint applied kind of sloppy completes them. I think a nice wreath of plastic sunflowers may be on its way!
