There is no tutorial. These are a purchased item at this link. I like this idea for a nightstand by the bed. 8"x8" routered boards with 8" gap between shelves.
I can imagine doing something cool with photos + vintage industrial metal grating (not a memo board, but maybe clips+photos?)
for all those prints that don't have frames... via apartment therapy. I like the idea, but it would be nice to just uses the wood, tie raffia, string or ribbons around the edges to hold it together, and remove the hardware. ~ETS
