Here are two of my screw ups. When I set up for the dado routs for the dividers, I forgot to take the length of the miter into account, so the outer compartments are too small. Also, for some reason, I got it in my head that this had a painted bottom. I didn't realize it until after I had glued it in. I didn't use milk paint, but I got some sample sizes of a few colors that I thought looked good. I used plywood for the dividers and bottom.
