After using the six odd boards from the reclaimed futon frame for my personal experiment, it's time to move on to the production piece.
Each of the twelve remaining boards measures 51-3/8 x 2-1/2 x 3/4 (inches).
Two similar panels are constructed as above, and interlocked below.
The back half of each shelf is then attached.
This detail shows how the two pieces of the frame interlock.
The connection is made with dowels so that the case can be split apart and transported.
If you give the objects enough space, as above, there will also be room to hang small art pieces within and around the two frames. I will move the Corner Bookcase into Hip Thrift tomorrow, so look for the update.
