When I was building two walls of bookcases in my living room, I decided to include decorative brackets that were a Thomas Chippendale design. I modified the proportions to suit my own purposes, but stayed pretty faithful to the Chippendale look.
Recently, (and 20 years after my bookcase design) I was going through some old family papers, and I found a photostat of an architectural drawing my father had done in the 1930s.
As I studied my dad's drawing, I saw a familiar shape in a detail. Then I realized that to achieve a furniture bracket, Thomas Chippendale had undoubtedly borrowed the silhouette of a column base and simply inverted it. That clever Thomas Chippendale!
