This week we have been getting an overstock of toilet paper rolls in our house. We thought about throwing it all out then we thought of a way to re-use and recycle these toilet paper rolls. To make it, I just took an empty shoe box and some toilet paper tubes cut to the same height as the box, then stuck them into the box together standing up. No glue, no nothing. They stay up fine on their own and I like that they can move a little to accommodate the pens, pencils and markers that will be coming in and out over the years to come.
