I live in Portland, Oregon and found Snow Days as a very tempting fabric. It's still available online, in yardage as well as jelly rolls. I would do a fabric search at
www.fabshophop.com, go on e-bay, or simply type in Moda Snow days yardage into your browser. I noticed that you put in a nonblue color in at least one pinwheel; you could use that fabric for one of your borders. Good luck.
