Last year, I ate a lot of nuts. And since I wasn't buying them in bulk, I made myself keep the packaging. As evidence of my nut habit. But also as a reminder to myself to stop buying pre-packaged nuts!
I knew I'd find a way to use the containers (did you see my nutty lamp?) but I had no idea what I'd do with the lids... until my daughter asked for a mobile. And then the wheels started turning!
