Finished French Country Wedding Bells by JBW (I'm actually ahead of schedule on this gift!)
NSLNS kitted it up with one 5-yard WDW. The names of bride and groom were not long names, and you know I'm extremely thrifty with my floss ... I finished with only about 6" (2 ply) to spare (14/28 count). Quick, easy stitch, but if you're not as careful as I am with floss usage, or you're marrying off a Christopher or Elizabeth rather than shorter names, you'll need more than 5 yards.
