Or, cut the card into an interesting shape around the picture, such as a diamond or teardrop or star. Glue them onto ornament shapes cut from construction paper, lace paper doilies, felt, painted cardboard, craft foam, etc. Punch a hole near the top and thread with ribbon or yarn. When finished, pull the spiral slightly so that it will hang three-dimensionally like a Christmas tree. Use a pin to poke a hole in the top center of the spiral and loop some thread to it for hanging.
Decoupage is simple and fun.
You can find books from the library describing the technique and ideas. Basically, you cut out the picture you like, use decoupage glue to adhere it to wood, glass, ceramics or cardboard and then seal it with the glue. You can decoupage furniture, glass plates or vases, homemade clocks, picture frames, serving trays, etc. The possibilities are endless. Make a special Christmas vase, or decoupage a Christmas stepladder for hanging ornaments on the tree.
