The basic crown portion, 3 pieces. A base 3/4' x 1-1/2" tall piece that has a kerf cut along its length and a small cove on its bottom edge. Then a 1/2" x 5/8" piece with a small cove at the bottom edge, even with the top of the base piece and another the piece with the same dimension but with a round over on the bottom edge that sets under the base piece.
These are all attached to 3/4" x 2" pieces that are securely attached to the separate units.

I just drew it. ;~) Crowns are easy if you make them from built up layers of wood and just about anything looks good. I actually built the crown on the cabinets rather than before attaching.
Thank you!
