Very cute! I once made a set of these, nesting inside one another in three sizes for my sister who was travelling a lot. She loved them. The smallest bag she used for her jewelry, the largest one for bras, and the middle size for pantyhose. They helped keep her luggage and motel room sorted. And you are right. It is a very neat pattern, and really not that hard of geometry to figure out. Great job!
oh what a neat idea! I don't think my math skills are sharp enough to figure out nesting ones!
