(Side note: it's completely acceptable and possible to pull off a yard sale in 30 degree weather.)
This is the second year so far that my Grandpa won't be with us for Christmas. He was quite a guy. One of his amazing traits was his tradition of wrapping presents with the Sunday funnies. This year I decided to wrap all of my gifts in newspaper. I also got used books from Wonder Book (one of my favorite places) and used them as gift identifiers - instead of name tags. I then tied them with love and Sugar & Cream yarn.
Not quite the same, but makes me think of him nonetheless. He and my Grandma would be quite proud of my use of resources and frugalness. Some other things they liked to do at Christmas were eat fruit cake (ew), bring the ham, take little naps on the couch, pet the cats, give the greatest, most random presents, and tell my mom that she put together a "veritable feast" at Christmas dinner. While we will miss them again this year, we will think of them with fondness and utilize all of their quirky sayings.
I can't wait.
P.S. what sorts of awesome things do/did your Grandparents do at Christmas time?
