Around the Corner Bookshelf

Attach 1x2 side trim pieces to the 1x12 side panels, drilling pocket holes along the front and back edges for attaching legs. Attach legs to the side panels with pocket hole screws.

Attach top supports to the legs. Attach side trim to the middle shelf, then attach the whole trimmed shelf to the side panels.

Attach side trim to the top piece, then attach the top to the bookshelf base. The standalone main bookshelf is now complete.

Build the corner add-on's third side panel the same way as the main side panels, and attach it to the completed main bookshelf with pocket holes.

Add the middle shelf with 1x2 trim pre-attached, then the bottom shelf with 2x2 trim attached. Build and attach the corner add-on top.

Nail or staple the optional back panels on with glue. Sand all surfaces and apply primer and paint, or stain and poly.
