How to make a personalized jigsaw puzzle

Step 13 Tracing more roads

The yellow roads are traced next. I started at the top right point and traced around the entire outside shape. I then went and traced the internal voids and I show how to join them in the next step. I didn't worry about where it crossed over the main road, I thought it easiest to just keep it one continuous shape.

After I had finished all the outline i applied a light grey fill to the largest shape. Note how all the internal shapes are filled as well. The next step shows how this is remedied.
