The minimum tolerance waste policy we have here right now results in the washing and reuse of the few plastic baggies we still have. We are also reusing bread and other bags for these purposes and I hope by the fall start of school to have some reusable fabric snack and sandwich bags/wrappers for all three of us. So I know you can get those funky sandwich bag drying rack things for this purpose, but I have more important things to store on those shelves (ie: pasta maker, juicer, assorted baking implements, food, food, food) so here is my current tool. The girls climbing tree. The short branches make the perfect length to hang the bags on and it feels a little like hanging laundry out to dry. The only important thing I found is to make sure there are no creepy crawly things in there when I take them down because who wants crunchy bits in their sandwich, blech.
