That's sort of a pun, I guess, as I think this ottoman, with its rich colors and texture, would have been quite at home in a seraglio of the original Ottoman Empire. Angelo seems to think so too, and he's definitely a creature who likes his creature comforts.
I began at the top, following the granny circle pattern so well explained by Raymond's mum at http://crochethealingandraymond.wordpress.com/2010/11/11/revisiting-the-granny-mandala/. When the circle was big enough (and by big enough I mean about 1 round short of covering the top of the ottoman, since I wanted it to have to stretch just a bit for a snug, not baggy fit). I just changed colors as the mood took me, but when the top was big enough I then did 2 rounds of single crochet, 1 in gold, 1 in ivory. There's no increasing after the last shell round of the top.
Your colors will vary, of course. The colors in the pictures look different because I took the one below in natural light at sundown and the one above with a flash to make sure Angelo didn't just look like a flat shadow. The true colors of the yarn are somewhere in between, but closer to those below.
