Cut out 2 Christmas card scenes, exactly the same size. Put them back to back with a small bit of polyfil in between so they're not completely flat. Set aside. Cut 2 pieces of clear vinyl larger than the cards, by about 1/4" all the way around. Using a tapestry or other yarn needle with a sharp point, and some decorative heavy thread or yarn, stitch the vinyl together about 1/3 of the way around the edges. Insert the cards with the polyfil between the layers of vinyl. Continue stitching. Try to knot inconspicuously. Add a hanging loop.
