How to draw a shamrock
Draw a circle that's the size you want your shamrock to be.
You'll be erasing this circle later on, so sketch it lightly. For now, you'll use it as a reference point for drawing the shamrock's leaves.
The circle doesn't need to be perfect, but you can use a protractor or compass to draw it if you're having trouble. Make 8 small circles around the inner perimeter of the circle you drew.
