The stonework method I'm using for this project is a first for me. The stones are made from egg cartons! I painted the inside flat surfaces of the egg carton lids with about five different colors; grays, tan, black and slate blue. Then, using scissors I cut each and every stone in random sizes. Using tacky glue, I started putting up the stones on the walls one by one; like a puzzle. The room shown here will be the entry room of my office.
