I am working on the hexie hill in My Small World right now. It's quite fiddly, but I'm dreading the New York Beauty-like hill so skipped it until I can figure out how I'm going to do it. I ended up appliqueing the rainbow hill - I started with the largest half-circle, then added each succeeding half-circle on top, cutting away the previous half circle underneath. It looks good. This quilt is quite a good learning experience!
