I have been making some clothing for my nephew and niece with some fun fabrics, and I had lots leftover. I wanted to use the fabrics in another functional way that would be simple enough to make. Then it hit me. My bento bag is boring. I decided to go overboard and make these three. I really like how they turned out. They fit my everyday bento as well as my one-layer Ponyo bento. I would say that multi-purpose = WIN.
