I can not build projects according to a plan, so I make mine up as I go along so if a step seems strange to you that is why. Please don't feel this project is to hard to try, it is really straight forward for someone with basic woodworking skills.
To start you will need a large piece of wood or plywood. The size on the wood will depend on the height and width of the shelf you want. If you want to duplicate this shelf all the dimensions are available on my website listed below. Add painters tape diagonally across the wood, this serves as the cut line and prevents the wood from splintering.
