Princess Feather

I went shopping yesterday to pick up a few more fabrics for my Roseville and while I was looking found a wonderful background fabric. I have my plate full right now but wondered if anyone could tell me how large the blocks of the Princess Feather quilt are? We have a king size bed and I wondered how large the quilt would be with 3 X 3 blocks instead of the 2 X 2 that the pattern shows.
