@wow, Thank you, and good question. The ends of the front/back, i.e., both the raw plywood and the drawer bottom notch, are only visible when the drawers are open, so I did not feel that it was necessary to "finish" them. After all, the purpose of using the prefinished drawer stock is to avoid having to do any finishing. Also, portions of the ends of the front/back are covered, in any event, by the drawer slides mounted on the sides of the drawers. I guess I could have mitered the corners which would have made using the Domino (with 4 mm dominos) a bit more difficult, but most people don't even think of that question; nor do they look at the drawer sides when the drawers are opened, so you must be spending too much time being snowed in up there in the north country. [wink]
Now, if you're wondering about the drawer bottoms, it turns out that the prefinished bottom stock (4' x 8' sheets) is also finished on one side (hopefully, the side facing up when the drawer is assembled), so if you should happen to show up at David's to do a closet inspection, I will be sure to tell him to keep the closet lights off.
