The longest line

You need:

1. white drawing sheet 15 by 15 cm
2. black fineliner
3. markers

I found this lesson on Artsonia. Start in a corner and draw ONE line, the longest line: curved, straight, zigzag, with angles etc. The line has to fill the whole sheet and you may not pick up your marker from the sheet! The line may not hit or cross itself. And, the most important: the line has to end at the point it started. So be sure you're back in the beginning in time!

When ready, draw with a pencil three or four geometric shapes on your sheet. Choose three colours marker per shape and colour them. Outline your shapes with the black fineliner.
