I would like to clarify something, the block I chose to put on the back is not in any way considered as a "throw away" or inferior block by me. One has to go to the back as a simple math issue, the choice was made based on the color story layout I have planned (I just told a fellow boomer I may dance naked in the moonlight, but I do it in an ordered row! lol) But do not despair a cool back has been planned w/ that singleton as the center attraction.
