I finally got my act together this week and continued work on my closet. I varnished the top shelf and did two coats of shellac on all the rest of the woodwork. (I used varnish on the top because I was hoping it would be more durable when we slide tubs and boxes across the surface.)
We still need to finish making shelves for the cabinets. Unfortunately, the guy we hired to help us with this project cut the wood incorrectly and now we have to either buy more sheets of plywood or piece some of the shelves. Right now, Jeff is trying to piece the wood.
