Op art around an eye

You need: 

1. drawing sheet 20 by 20 cm
2. ruler
3. pencil
4. post it 
5. black markers

Step 1

Draw an eye in the middle. 

Draw lines from the eye to the edges. Important: this must be an EVEN number of lines, otherwise you won't be able to color a checkerboard pattern later.  

Step 2

Put a post-it on the eye. Be sure there will be place for another one later.  Draw dots on the cornors with a pencil and connect them.  

Step 3

Do the same on another part of the sheet. 

Step 4

Trace all lines with a fine black marker. Draw alternately dots in the shapes that must become black. Color them with a bigger black marker

Stap 5

Color the iris of the eye with pencil.
