Here is a window style pop up card for Easter.
I found the lamb and bunny paper cutting pattern at MCTSCAL efiles.
After cutting this card I decided to edit out many of the tiniest cuts, so yours will look slightly different from mine. Believe me, your fingers will thank me for it!
Pinch the little side folds between your fingers just enough to set the creases (valley folds).
Crease the long horizontal folds. The top one is a valley fold, the middle one is a mountain fold and the bottom one is a valley fold. Push the card from the back and collapse it flat.
Glue the cut card into a background card, matching center folds.
Refer to this window card post for additional assembly instructions.
