I've been wanting to make a Card in a Box for a while now and decided to try it out for a special friend's birthday.
My starting point was the patterned paper, "Black & White Diamonds" by Canvas Corp. All the dies are from My Favorite Things: the "happy birthday" die, the "Balloons STAX" and the You Rock from "Blueprints 11." I used shrinky dink instead of acetate for mounting the stars and balloons.
