Thank you so much for these plans! As soon as I saw them, I knew I HAD to build it! I absolutely love it - and now all my friends are asking for one!
I chose to use 3/4" plywood for the back board as it's what I had on hand. I used my kreg jig and just attached it with pocket hole screws.
Edited: After posting pictures of my finished shelf on facebook, I've had friends request I build them shelves. I've just completed my NINTH shelf! The picture shown is the first set of 3 that I finished and have already been delivered to their new home. :)
