Class started by practicing with two colored pencils taped together to create a double line drawing tool. One pencil should be forward of the other a bit. Practice straight lines, loops, circles, ribbon like swirleys... and curlies. Try looping around to make a wreath. We should have tried trees too.
Then we practiced imagining spheres as we drew. A simple round circle with a circumference can turn a flat disc into s sphere. Try the atom symbol. Try winding up virtual yarn to make a bigger and bigger ball of yarn. Try an orange with the peel scored. Finally try drawing a sphere by coloring in the imaginary outlines but leave a white belt as a white ribbon.
Write a simple greeting onto any spaces you want on your card.
We drew our cards on folded card stock. Either as two cards from a sheet or one full sheet. I trimmed off one end of the full sheet folded. It is a bit better proportion that way.
Here they have arranged the display of the class work into a tree shape.
