Finding a bookcase that is just right for where you want one is tricky, but with just basic woodworking skills. It's quite easy to make your own. All I needed here was a saw, plane, sandpaper, drill and screwdriver. Some bullnosed hardwood window sill, a sheet of plywood forr the back and screws and brackets. Unlike mdf or laminated chipboard they don't bend with the weight if books and love a bit of polish! We wanted one to fit this space in the hall. The only bit that took some time was rounding the corners and matching the contour of the edge. (note my wife's "coathanger decoration").
