I'm sorry... I have studied what you're saying & showing and I can't understand how you are doing it (making "C"?).
A B & C look like the same size to me...
Do we slice up existing molding "A" & "B"... except "B" spacing of strips starts the opposite way as "A"? Then glue them back together to form "C"?
... from what I can see... why didn't we just use "A", or "B" as "C"?
I'm missing something... am kinda dense... all of which isn't anything new...
Thank you...
