I finished this cozy today. It just needed a button to help it stay closed.
Well, I wanted to hold onto the paper that the buttons were attached to. So I made a matchbook notebook out of it. Then I looked around and saw some mail from my old college. I made more notebooks. Then I made some out of 3 cereal boxes and a ripped Christmas gift bag. My toddler really loves coloring in the large cereal box ones. These are perfect for carrying around in your purse, wallet, or pocket when you need to write a quick note, phone number, or whatever.
You can always embellish them, but I didn't.
