Housewarming idea and no time to make a big basket of goodies? Simple idea- a good wine he / she or they will love. Go to a $1 store (most will carry a basic wood handle hammer) attach hammer around the neck of the bottle. Write a cute card and make sure to include the saying "it's time to take a break(or break something) from a stressful move! congrats on the new place - now go get hammered!" Just make the saying your own that works for the theme!
