We came across these fun mustaches at the party store, 12 in a package for $4. Amelia did the heart drawing and wrote the message (under the mustache it says "moustache"). I scanned it all in and gave it a fun background and colored the heart red. We were going to use glue dots to stick the mustache to the card but the paper backing so was slick nothing would stick to it. I even tried the glue gun and that was a bust. So we ended up just taping them on... not as pretty but it works!
I think the kids in her class will sure get a kick out of them!
