Easy Tessellation Lesson using Pencil and Tracing Paper
Step 7 of 16
7. Draw a weird squiggly line on the left side of the rectangle* on Page "A".
Use pencil. Draw lightly; don't push hard.
Use just 1 to 3 waves. The more waves you use, the harder it is later.
Do not copy my line. Be original!
* A rectangle is easy, but any parallelogram is OK.
