The large cabinet sides you've made from expensive walnut plywood look great. The dadoes and rabbets are straight as a string, and the dimensions are right on the money. Unfortunately, they're both left sides.

shop tip

Masking tape can keep you from making the right cuts in the wrong places. Mark the good face, top, or back of the panels with masking-tape labels. The reminders or special instructions that you write on the tape prevent cutting errors and also will prove helpful at assembly time.
