Oh how do I love this class. Watched it while at work and used a Post-it sticky 3x3 to make the block. Later saw that I have some extra space. Just happens I had a small sheet of tracing paper in my 'work sketchbook' that I used. My tools were a Paper Mate marker, copy paper, Post-it and the tracing paper. I can hardly wait to try it again. Thanks Lucie for teaching such a great class. You are so resourceful with the simple tools you use. 

This was a photo copy of the tracing paper. I accidentally drew a guide line...with the marker!?!
