So the wife needs a new place to put her coffee cups! No problem, that should be a pretty easy one. For some reason though, if you ask her, there is no finer wood on the planet than the stuff you pull off old pallets, so I rescued one of those from a dumpster and pulled some boards off it and went to work. My plan called for hanging this from the top of our cupboard, which is a thin sheet of fiber board with a protruding edge up top. I cut a small piece of a board, notched it a touch with a coping saw, and screwed that to the back of the highest frame member so the cupboard wall will slide neatly into the notch.
