We were able to get the theater room and craft closets textured, primed and ready for paint. I installed the counter tops as shown below. The black counter with the green painted pegboard actually looks good (I never thought I would say peg board looked good...)
Notice the two layers of trim at the top. The ceiling in the closet is 1 1/4" out of level due to the house sagging over the years. The stone fireplace upstairs was not adequately supported (now it is), causing the sag. The lower layer of trim is even with the pegboard holes and the upper layer is partially cut to match the ceiling. It also runs a bit out of level, splitting the difference. All this together effectively hides the out-of-level condition, especially once the closet doors are added.
We bought the laminate counter piece at Home Depot - $78 for an eight foot piece. The other half went to the other craft closet (one for sewing, one for stamping, paper crafts, etc.) It seems like a nice high quality surface, with a fully wrapped front. I cut it with a new carbide saw blade on the table saw, and had no chip-out.
My DW will keep her sewing machine and surger on this counter, so they will always be ready to use. To keep the counter from sagging over time under the constant weight, I added these heavy duty shelf supports (rated at 400 lbs). I quickly painted the wood backup pieces once I installed them, which helps me avoid extra masking. I also glued and screwed a fir 1x4 across the front behind the counter lip.
Next I need to make a couple of shelves for the top of the closet and 3 drawers that go under the counter. After that, my DW will get all the pegboard stuff.
