While picnicking with a friend, I noticed she had an adorable re-usable snack bag that she received as a gift. Since I had extra fabric from the boys sunglass cases, I decided to make three. I did some searching on the web for a tutorial and I liked THIS ONE best. I wanted to find one that had minimal seams inside so there would be less places for crumbs to get stuck.
I'm pretty impatient, so I had to adjust the size of the snack bags to suit the short strip of velcro that I already had on hand. I settled on 5.5 inches by 6.5 inches. I saw some cool interiors made out of a wipeable material, but also saw conflicting opinions about how food safe the other materials are so I stuck with cotton fabric inside and out.
Instead of grabbing a ziplock baggie for snacks when we're on the run, I feel good about grabbing our re-usable snack bag. (Or "cracker case," as Aaron calls it.) When we're done with our snack, I shake out the case and wash it once a week. (I'm not using them for anything sticky or gooey... that's just too messy!)
