Draw a wavy line across the paper.
Above the wavy line draw an arch that curves up.
Continue adding arches that build on one another until you reach the edge of the paper.
Below the wavy line draw arches that curve down.
Draw the same curvy lines making sure they connect to the side of the other "worm".
Continue drawing "worms" until the entire paper is filled.
Choose a pair of complementary colors (red and green shown here) and color in a "worm" with those colors.
If you want, choose a different pair of complementary colors for the next "worm".
If you'd like, choose another complementary color pair for the next "worm."
Continue until the entire drawing is colored. You are finished!
