One update was adding elastic instead of using ribbon to tie the roll up, which makes it easier for little hands to put away. The second update was using iron-on vinyl on the back piece of fabric so that the waxy crayons don't mark up the fabric.
The third addition was to make an accessory to go with the crayon roll. I cut up some cardstock, punched a hole in each piece, then used a metal ring to secure them together. This way, mom or dad can pop the crayon roll and the paper into their bags and easily pull them out when they need to entertain the kids (at a restaurant, for instance).
Creative and in expensive additions to this already cute and functional craft project!
