If you check out the blog post, you can get all the details, but I can tell you the basics here. The background panels are made of quarter inch plywood with picture book pages by Oliver Jeffers. I used two books, and used cutouts from one book to paste on the layouts of another book. Ritter cut the shelves, painted them, installed the brackets - pretty much everything except the paper part. We used vintage maps to outline the panels and on the tops of the shelves. On the bottom two shelves we installed clear base plates so that Nuelie could build on them.
