Although both are pentagon designs, Phi Cowl(below) is knitted flat and each pentagon seamed. You can buy it here. Phi comes from the book I was reading at the time, The Golden Ratio, by Mario Livio about the golden ratio(phi) and it's geometric relationships to pentagons and other figures.

The Deanery Street Centerpiece is knitted from the outside and ends as a single stitch at the center of each pentagon and you can buy it here.
