It may be a bit early to start making drawer pulls for this project but I think pulls, knobs, and other hardware should be considered as much as any other element. Remember Walter Gropius and the Bauhaus theory of "total design"? Every component should be functional and intentionally designed to be supportive of the entire constructed piece.
Walnut and ebony pull prototypes. The upper row has hand carved dimples underneath as a little tactile surprise. I think I will go with something from the bottom row, however. The cabinet is brutal in form and a pull that is similarly planar will fit its gestalt.
