- pop-up cards [www.http://robertsabuda.com/popmake/index.as. has some great ideas & instructions]
- use xmas symbols -- santa, tree, reindeers, gifts, poinsettias, holly, mistletoe, cookies, stockings, snow, snowman, wreaths, angels, star, the Magi, Jesus in crib/manger, ....... use an enlarged image/drawing of any single symbol or use them in combinations to create a scene/a story...
- use xmas colors - green, red, white along with some glitter. go surrealistic or neo-modern!
- glue stuff instead of or along with artwork -- stickers, glitter, dried flowers & herbs, color/printed paper cutouts, wool, yarn, fabric, cotton-wool, sequins, beads, metallic wires, laces, origami, satin ribbons, etc....
- make a globe & encircle it with poinsettia or holly garland, showing how the entire world is united in celebrating.
- make it humorous - add some cartoon characters - make it into a cartoon strip or a christmasy scene. do this for small kids - they'll love it!
- do a mix & match combo of the above
hope these inspire you & get you started
all the very best & have fun - let the creative juices flow :-))
