I know these have probably been done to death, but this is the first time I've ever attempted a project like this. I made these gift bags using grocery flyers. I used cereal box cardboard to line the bottom, since I'm giving heavy gifts! They seem pretty sturdy and they only took a little while to make. I think they are a lot more interesting than traditional gift bags, and I love that I got to re-use the flyers.
I like this one best because of the bow.
The string is made from paper too, just twisted like rope.
