I rarely buy Christmas fabric. When I was younger, we decorated the whole house, even bathrooms. Now I have to work myself up to even put up a tree. Kids grown and gone, may or may not be here for Christmas, which I try hard to be nice about - we have to share with their "other" family.
Generally, I'd prefer a "winter" theme, so that it can be out longer. I did just buy a Father Christmas panel so I can make a Side Lights quilt; they are quite easy, so it won't take long at all.
I'm not into fabrics with metallic at all, which knocks a lot of the Christmas fabrics out right away. I have been noticing some of the ones that are red and aqua lately - but still don't want to buy something that I'll have out for a month at the most.
