After shopping for quite some time for the perfect lunch bag/box, my daughter found a picture of one she really liked in a Japanese magazine. Unfortunately the directions were almost undecipherable. So we found a bag of the size and shape she wanted and I drafted a pattern using the design elements from the magazine picture. It worked perfectly as you can see. And has the added bonus of being machine washable. By-the-way sushi is one of her favorite lunches.
