Unbeknownst to me, the finish panels are supposed to be flush with the doors or drawers. Below you see why.
Side Panel Incorrectly Installed
Much better when things are done right.
Correct Side Panels
Left Side Bottom Panels
Left Side Closeup
Right Side Bottom Panels
Lower Left Filler
Upper Left Filler
The
"bad cut" on the right side of the panel isn't due to my handyman
incompetence, but to my skill deficient antecedents. Yes, the
wall is this much out of plumb.
