Useful? I would say off the top of my head, I bought one of those wooden reindeer card holders. I don't have it anymore.
Stuff I still have and will pass on forever? Christmas ornaments.
I don't go to craft shows or buy crafts anymore.
My sister on the other hand has a house full of crafts. She has a "country theme" for her house. She has shelves, a cool clock, plaques wit sayings, furniture, etc....You name it she has it.
