This is my non-woodworker's tutorial.
Building by the Seat of your Pants 101.
I made two bases, one for top and bottom, and attached the side panels.
Added a bottom, then the bottom shelf.
For the top, I added nailing strips, so I could screw the top on from the underside and the screws wouldn't show.. then once the top was on, put another piece over the base so the workings didn't show.
I'm whipping right along ... well five days along ... and am really happy with how it is looking.
Just need to add another shelf, get the trim on, sand, prime, paint, antique, hinge the window and get that installed. .... what maybe 5 more trips to the lumber store??
