My current woodworking project is a Mission-style bookshelf that I designed to match the sofa table that I built last year. The bookshelf will sit below a window to the kitchen, so it is low and extra wide to fit that space. To support the weight of the books without sagging, sets of stiles transfers weight from the middle shelf to the frame above and below.
I am building the bookshelf out of cherry. Like the sofa table, all joinery is mortise and tenon. This time I am squaring out the mortises with a new set of mortising chisels rather than rounding off the tenons with a knife as I did on the sofa table — which is making the process go much faster.
If you like the design and wish to build one for yourself, you can download my SketchUp model as a starting point.
