Things I think are useful: A Plastic Bag Keeper
I think I'm the only person I know who uses this. I've read about how people really like it and I can see how it would be useful. But when you only have one friend, it's just not very exciting.
With my whole Earth Day epiphany, I need a place to put my plastic bags. I've always just crammed them under the sink. But this is a good idea! It's recycling all around! And I always thought holders like these were creepy.
