What a super idea! I have a bunch of my projects (PHDs - projects half done) in Tastycake boxes. They are sturdy and a nice size plus I get them for free when my brother up north sends them to us ..... full of tasty goodness of course. However, I have to open every one until I find the project I am looking for so numbering them and taking a photo is a wonderful way to fix that job. Thanks for posting that tip.
