This is a quick little project I whipped out for Huck. He needed a snack sack for summer school. It is a little smaller than a regular lunch sack-just big enough for a juice box,a pack of animal crackers and a clementine. It has a little strap on the back (that matches the lining) that he can either hold or sling over his shoulder. If I did it again, I'd probably add a stiff rectangle of something (heavy interfacing? plastic? something washable.) to the bottom of the sack so that it would hold it's shape better when it is picked up and loaded with yummies.
