I made the cabinet drawers from half inch birch plywood. I made the side pieces from some of the scraps leftover from the cabinets and two new sheets of plywood. I have three different heights of drawers wrapping around the kitchen. A deep drawer on the bottom, and medium drawer in the middle and a shallow drawer on the top. The joint at the corners and holding the bottom in place is a dado and rabbet fit together. The bottoms are also made from half inch plywood. I made a jig to hold the slides in place for instillation.
