I didn't make a craft with conversation hearts this year, but I really like them. Not so much the taste (although have you had the Sweet Tart ones?), but the cute little messages on them. Carolina from always expect moore made some earrings with them, which I think is genius. I never thought of them as jewelry, but what cute jewelry they make. You definitely need to visit Carolina's tutorial, because there are some tricks to getting the holes just right.
