When I started out selling folding shopping totes at famers' markets I designed a purse that would function as a fanny pack but NOT be one. Something I could wear comfortably and keep my valuables safe.. I sold half a dozen before I was able to keep one for myself and the popularity continues. While the sewing techniques and hardware have improved, the basic form remain the same. This weekend I had my eye on one that I had hoped to keep for myself.. and it sold, so the day after a grueling weekend I'm back at my work bench and I'm finally making one just for me.
