I have always loved the idea of reusable sandwich wraps like the ones seen HERE though I don't own any myself. When I read about DIY ones at THIS site I decided to give it a try. I hesitate to share my results as I am SERIOUSLY craft impaired but it is too good of an idea not to share it.
Basically you use the inside lining of a cereal box (being sure to use a cereal without BHT) and sew it to fabric. I had a fraying cloth napkin and an empty box of Cagadian Farms cereal so I thought I'd give it a try. :) For someone crafty, this could be a great project.
