I have been making and selling a lot of these pop-up box cards. This one is a birthday/celebrate card. On the back is a place to write a message and slip a monetary gift. I used die cut stars with glitter paper, balloons and a large swirl for the pop ups on clear stripes of paper for different heights. I do have to make special envelopes for these out of card stock for size and to add protection for the card. Come visit me at Willoughby's Farmer Market on Saturday mornings form 8-12 AM if you want to see them live.
