Step 1: Left side
Start at the pointy top and draw a long slanted line down and to the left. Stop at the bottom left corner.
Step 2: Bottom edge
Draw a straight line across the bottom, starting at the left corner and going all the way to the right.
Step 3: Right side
From the top point, draw another long slanted line down and to the right until it meets the end of the bottom line. Now you have a big triangle.
Step 4: Inner edge
Start at the top point again and draw a line down inside the triangle, leaning to the right. Then bend it and angle it to the bottom right corner.
Step 5: Two round eyes
Near the bottom of the big flat face, draw two round dots with space between them. Fill them in dark.
Step 6: Little smile
Between the eyes and a bit lower, draw a tiny wavy smile like two small curves joined together.
All done!
Go over your lines with a marker, then color it in.

Tips for drawing a glass prism
- Draw the left and right sides lightly first so both lines meet at the same top point.
- The inner edge is the trickiest part. Start at the top, go down in a long line, then make one clear bend toward the bottom right corner.
- Place the eyes low and wide apart, with the smile centered between them, to get a cute face.
