Swallowtail stamp Pop Up card, Retiring!
I have a circle cut from a window sheet using the smallest circle framelit of the Circles Collection framelits. I then spiral cut into the center of this circle, adding a glue dot on the center and then on the outside beginning of the spiral. This is placed behind the "free" half of the butterfly, then close the card. Then I added a punched butterfly to cover up the glue dot on the right side of the card. Small butterflies are from the Stampin'Up! Papillon Potpourri stamp set.
Front of card. This used retired Epic Day dsp. Made this card a long time ago, but it is a favorite.
