Here are some cute craft ideas I found on pinterest for Valentine's Day. All are made using felt.
This centerpiece is made from felt flowers. Very sweet. You could do all pinks and reds and use it for Valentine's Day.

I love the fullness of this heart wreath. So pretty.

And of course I love the Valentine fortune cookies I made last year out of felt. Very fun.
