Et voila! Shelves. I cut a leftover piece of wood from the dryer platform in half (with a handsaw balanced on top of my recycling bins because I was too lazy to get everything out that was needed for the circular saw), installed four of those handy braces I’ve been using forever, did some drilling, and now there are shelves where there once were none.
Here’s a close-up view.
In keeping with my laziness, I’m not going to paint them. The bare wood fits with the utilitarian nature of the laundry area.
