Paper Pieced Candle Birthday Card

Every year for Christmas, part of my gift to my parents is birthday cards.  I make enough for them to give to all of their kids, in-laws, grandkids, and throw in a few extra in case they need them for friends.  I've been on the hunt for cute cards that would be easy to mass produce, and here's one of the options I'm considering for this year.

The inspiration for these cards came from HERE.  What do you think?  I'm still searching for other ideas, so if you've made or seen a cute card on the web, could you do me a favor and leave a comment with the web address so I can take a look?  Thank you!!
