valentine's day crafts for kids?

[poprockgrrl.livejournal.com]

My gf has been asked to help her 10 year old neice's class create a valentine's day craft. The 2 of us have made plenty of valentine's day related things in the past, but she needs something geared towards 10 year olds that only will take about an hour. I've googled some things but they're kind of boring so I figured I'd ask all you craftygrrls for ideas.
Thanks in advance!
