Penny's Paper Crafty is Happy Birthday and at Designed 2 Delight it is "It's My Party". I created this gift card holder card last spring for my friend and I am sorry that I can't properly credit where I saw it originally. I used dp from CTMH and the stamp- which is sooo true is from Repeat Impressions. The HB punch is from Martha Stewart.
Edited to add: I found the tutorial! It is here: http://thecatspajamasrs.com/March2011.htm
