I'm not sure I'm following you so let me see if I have this right.... you are prebending 2 pieces of 1/4" baltic birch plywood prior to gluing the two pieces together which is the 2 plys you are talking about. Is that correct? And that will give you a little under 1/2" thick corner piece for the furniture (plywood being under nominal thickness like it is).

BTW sweet jig you built for the bending process.
