I found an inexpensive bookshelf at Walmart that somewhat matched the color of my kitchen cabinets. It also fits on top of my existing buffet. (I don't think my wall will ever hold another shelf!) I've been using it "as is" for that past month but wasn't quite happy with it. Here it is before the makeover...
I decided to replace the back with beadboard that I cut to size, stained with Minwax "Kona" and attached to the back by pre-drilling and nailing to the edges of the bookcase. I then decided to sand the sides and edges of the bookshelf with 100-grit sandpaper removing some of the original dark finish. Here it is after I sanded it...
I am much happier with it now and I think the beadboard and the sanding gives it more character...
Here are a few pics of my small kitchen and dining area...
