Today I sketched out my idea, made a cut list and then walked across the street to pick up supplies. It's great working at Gowanus. There's a lumber store on the block, another one street away, and Lowes a 5 minute walk in the other direction.
I picked up a sheet of walnut ply, cut, sanded, glued and drilled my Kreg pilot holes. Tomorrow I'll start applying the finishes. I realized late in the day that the edge veneer is going to change the size of the pieces a bit, so I'll have to trim back the boards before applying the edges.
