I designed and built this stereo cabinet using walnut veneer on Baltic birch plywood, leaving the plywood edges exposed. The sides are just Baltic birch. It's probably a love it or hate it look; the person I built it for loves it. The walnut veneer came from a single 14" wide board that I sliced into 1/16" veneer. The shelves are 13-1/4" wide, a single sheet of veneer covers each shelf. The finish is Rubio Monocoat. It's the first time I've used it and I'm a fan already. If it only yielded a little higher sheen, any sheen, actually, and I'd probably never spray finish again.
It's roughly 49" wide x 31" high x 14" deep.
