Here's a great idea for when you or the kids need a new pencil case. Make one from plastic a soda bottle instead of buying from the bookstore! You can also use this for other arts and crafts supplies (Bottle Bag Duct Tape)
Option Use I second piece of same bottle, make a pincushion on one end ( glue gun a ribbon to cover the raw edge) and the zipper for a sewing kit! Two plastic bottles and a zipper, nice small gift holder.
