YES! Glow bracelets tucked into printable cards (doc available at link) makes a trio of fantastic Star Wars Valentines for kids, nerds and nerdy kids alike. I love them so much, I won't gripe about light saber color accuracy (and in doing so give away how firmly I fit into the "nerd" category)
"The boys and I had so much fun making these, and I love how they turned out! (The “lightsabers” are bracelet glow sticks from the dollar store. I might try making some with Pixy Stix as well and see if they work out."
