When I made the books in Ghoulia's room, I cut out two 1 inch by 1 inch pieces of cardboard (you can use bigger or smaller, whatever size you want), glued them together, then cut pieces out of magazines I thought would make cute covers, wrapped it around the cardboard pieces only covering one edge, just like a book cover, glued it and then trimmed off any extra. Then I painted the brown edges white to look like paper. You can also make a book that opens if you don't glue the two pieces of cardboard together. You'd glue them flat to the "cover" then can cut out words from the magazine and glue them on the other side and fold it closed :) it's really easy. Good luck!
