This tubular art tote will keep your child's projects safe on those masterpiece-crumpling bus rides home.
Make the strap by unrolling about 40 inches of duct tape and laying it sticky-side-up on a table. Place a second strip of equal length on top of the first, with the sticky side down. Carefully press the two together.
Attach the strap to one end of the mailing tube with duct tape. Measure the strap so that it'll fit comfortably across your child's chest, then cut off the excess and attach this end to the tube with tape.
Wrap tape around both of the tube's ends a few times. Have your child decorate the tube with permanent markers.
