Scrap wood shelves

The kids and I worked together to make these shelves from wood I dug up in the scrap pile. I had to be creative to come up with enough wood of the right dimensions, some of the 1x4's started life as 1x6's and the front pieces are baseboard moulding. I didn't use a back piece because it seemed sturdy enough as is. I used removable velcro type hanging strips to attach them to the wall.
