Avoid having to spend a lot of money on additional accessories for your American Girl doll. This video tutorial outlines the steps to make a juice box for your doll. You will need an empty juice box, unfold the tabs of the box, and then flatten the box out (so that it is no longer a box). Wash off both sides and scan this face down. On the computer, reduce the image size of your box and print it out. Wash the original straw and cut it to the size of your new box. Score this printout, which makes the box easy to fold. Layer pieces of foam together (approximately five) to get the desired thickness of your juice box. Then, glue the box template around the foam and you have created the box. Then, hot glue the straw the box, and you're done.
