For the kitchen cabinets, I built face-frame cabinets. They have a solid wood 'face' in front of the plywood boxes. It's the traditional way to build a cabinet and it makes for a very strong box.

But for the bathroom cabinet, I wanted something a bit more modern and light. And that would be frameless cabinet construction. If you've seen Ikea furniture, you've seen frameless cabinets. Instead of having a solid wood face, it only has a strip of wood veneer covering the edge of the plywood. Known as edge banding, it has heat-sensitive glue on the backing. You iron it on. Yep, iron it. Then you trim it and sand it. So I've been edge banding lately.
