The guy put together the latest couple of storage shelves. I was going to stop getting these light plastic shelves, but then Jon brought up that his are all like these and reminded me of the basically zero labor cost. Then, I reconsidered.
Today, I found that the lumber alone (using 2x4s and “oriented strand board”, nothing fancy) for the storage shelves would cost about as much the plastic shelves.
Then, I had trouble figuring out the environmental impact of lumber vs. the petrochemicals needed to make the shelves, so I just mentally gave up and got the shelves and avoided the struggle of making shelves.
