I've now watched the first 12 minutes, and it looks like the whole film is about plastic bags -- not bottles. I agree completely about using your own bags instead of grabbing plastic grocery store ones when at all possible. But Dream Green batting is made from recycled bottle, and it is a wonderful product. It "sticks" to fabric as well as Warm and Natural batting. I like the idea of taking those plastic water bottles out of the equation. Let me know if I need to watch more of the movie, but already doing my part about bags.
