Dipped Cards from This Heart of Mine
Amy has a great tutorial for creating gorgeous dipped cards. They are perfect all occasion stationary and would be a great handmade gift. As a bonus, when she hung them out to dry, I think they made a fun garland that could be used to decorate for a party. Then when the party was over you could actually take them down and use them as cards instead of tossing the garland in that garbage.
