We did some pumpkins too. I tried to add some dry ice in mine and got a pretty cool effect.
Amy made some sweet Halloween cupcakes that were a hit at our party, but were so cool that people were afraid of eating them.
This year Amy and I were Ketchup and Mustard. The costumes were very comfortable. We couldn't find yellow pants, so we got grey sweat pants and dyed them yellow... and it worked, mostly.
