I really love unusual colored pumpkins...
our local arboreteum has a gorgeous display of them every year.
The varieties and colors are amazing.
This year I knit a turquoise pumpkin to go with my orange ones. You can find the pattern here... http://www.woollysomething.com/tools.html These pumpkins are so much fun to knit... they take a couple balls of yarn and then you felt them.
The turquoise is so cute with the orange. It also happens to go with my living room.
