Well, perhaps easy is the wrong adjective... at least for abstract reasoning-challenged me. It just might be Christmas before I get the weaving sorted out!
But if you're the type who takes to paper engineering like a duck to water, the eye-catching hearts would be perfect as favors filled with treats for a wedding shower, baby shower, or birthday party.
Thanks to Pam at Gingerbread Snowflakes for sending me the link. She wrote a tutorial [edit: no longer available] that shows how to construct the original woven heart and it's honestly fun to do - give it a try even if these look too complicated. I remember having a great time making red and white ones for Valentine's Day and filling them with Hershey's Kisses when my boys were in kindergarten.
