I have been a little out of my DIY mode lately. Mostly just feeling very passive. But as I mentioned before, I have gotten SO sick of having to shut our coat closet really quickly so that nothing falls out. Or feeling embarrassed when someone opens it. Meet our mess. (Just keepin it real people.)
(Sorry for the suddenly terrible photo quality. It was late!) I simply layed my piece of wood across the two supports and tacked it there with a thinner nail on either side. The top ones are not nailed down at all and it really is not necessary, but i didn't want it sliding around. next I found a piece of scrap trim that we had in the workshop and cut it the same width as the shelf.
