I'm not usually a big advocate for favors (this isn't the Oscars, you don't get a goodie bag), but these were easy enough that I just went for it. They helped pull in the color scheme and will be a nice treat for the guests after they leave. The concept: chocolates in a custom bag, arranged like a candy shop.
Glue your labels onto white paper bags (mine were $2.50 for 12 at the craft store). Use a glue-stick or tiny dots to avoid that wrinkled-glue look. To spend a little more, you could print your labels out on stickers (address labels or name badges).
After filling the bag with your treat of choice, fold over and punch holes. String ribbon through from the back and tie a knot or bow in the front.
Arrange on a bookshelf that is magically clear thanks to that fact that you're moving in a week and a half. Voila, instant candy-shop feel with 24 bags, 12 pieces of paper, lots of chocolate, and two spools of ribbon.
