Nan,
Oct. is Fall or Halloween. Defer to partner. Unless you are truly offended by Halloween. Then, just do a Fall postcard. I personally LOVE Halloween. But, I am going to do a Fall pumpkin instead. That way, I will not offend partner.
Nov. is Sweet Treats. Or, in the Kitchen. I'm not sure why, but some people do not want to do a desert related postcard. There are absolutely no broken diets or unwanted calories. So, you ladies decide your direction with that one. There are some darling themed kitchen fabrics out there.
Dec. Winter. (Not Christmas) So many fun ideas for Winter. My mind is already racing with them.
Have fun.
Maxie, loved your postcard also. Nice job!
