We made perfect sized dolly lunch bags by cutting open a regular lunch bag and cut a square piece big enough to wrap around a juice box. (approx. 5-1/2" long by 7-1/2" wide) The 6.75 oz. Hi-C juice box is the perfect size. The shorter fatter ones won't work. We used the fancy Fiskar scissors to cut a zig-zagged top on our bag, wrapped it around the juice box and fold up the bottom end (like wrapping a present). We used a glue stick to secure it. It is just the right size for the dolls and my DD had a great time using Sculpy to make some food and packing her doll's lunch with pieces of tin foil and cut up napkin. Then we got even trickier and used the glossy solid color wrapping paper to make colored lunch bags and decorated them with stickers. Could be party favor bags for a dolly birthday party, too.
