I have my extra feet in what is probably a jewelry travel case with clear plastic pockets.
However, an idea a class mate at a quilting class, of course, we is to keep her feet together with each foot in a small plastic bags and then used a single ring holding them together ... and then keeps them together in a cute little storage bag she made. Each little plastic bag was labeled.
I'm going to use her idea together with my jewelry travel case.
