I wanted to ask a question about today's lecture on Frank Lloyd Wright. I know that he conceptualized all of his architectural designs, as well as most of his interiors, but i wanted to see if anyone knew if he did his own decorative work, or if he had it commissioned. We discussed how he was influenced by Turkish ornamentation, and then showed the design he used for the Cutts House, but i wa wondering if that was his own design, or someone else's he used in his architecture. Does anyone know the answer to that?? Also, there is a reoccuring theme of the materials he used in his designs, and was wondering if it was simply red brick on the exteriors, or some other type of stone?? This can be seen with the Robie House, and well as most of his Prairie style. Thanks for any input!
