I picked up some very nice quarter sawn sycamore yesterday. I think the sycamore will look good as a lapped back for the case. I'm looking for a spalted maple board to make the door panels, if I'm unable to find what I'm looking for there are a couple sycamore boards that would make attractive door panels.
I still haven't worked out the interior, how many shelfs, where, and/or drawer or no drawer, or even several,
I guess after three years there is no need to rush.
