One of my favorite combos is blending chalk pastels over dried glue. When I saw this cactus illustration, I knew it would make a great image and allow for some simple shading practice.
- Black construction paper, 9″ x 12″ or larger
- White glue
- Chalk pastels
- Spray sealer (optional)
- I used 9″ x 12″ black paper, but recommend something larger for 1st or 2nd grade students. I had to really be careful to keep my glue lines from touching each other, so a larger format would make it a lot easier.
- After drawing the cactus in pencil, trace all the lines with white glue. Important: Let dry flat or else the glue will run and make messy lines.
- When dry, use chalk pastel pencils to fill in the cactus. I decided that the light source was from the left, so I used a light green on all three left sides of the cactus, and a dark green on the right. I also had a medium green to fill in the middle, but you could just used two colors that meet in the middle.
- Fill in the sky, ground and rocks with single shades. To finish, a little white pencil made highlights on the cactus, and a little black made a ground shadow for it and some rocks. Spray with a sealer or hairspray when complete.
