For my daughter’s 9th birthday, I wanted to figure out an activity that would also work as a party favor, so I brought home some leftover supplies from a story we did at Martha Stewart Living, which was about clever updates on camp crafts. The girls made necklaces, and they were a huge hit…even their moms wanted to wear them when they picked them up. The round beads cost $8.75 for 100, and the plastic lanyard/lacing is $3 for 100 yards. It’s nice to get it in several neon colors. But if you think about it, you could get away with spending less than $30, and having an activity (with no clean-up) and a favor, for at least 15 kids.
