I don't know how to build cabinets, but I have some ideas. I need to get a counter in the kitchen of this tiny house I've been building. I need to decide on a place for the sink, and a place for the tiny oven. Then I need to build a structure to keep those things in their place.
I'm not a carpenter, and I'm not in any danger of becoming some great woodworker. I basically waited until the last minute to start poking my tape measure in all directions. All that did is confirm that I have no fucking clue what I'm doing.
Instructions for cabinets include lots of expensive plywood. The benefit is that there are instructions. I'll try again next time. Today I built something that functions more as figure 8 than anything belonging inside a house. Strike one.
