1. Start with a Horizontal Line
Sketch a horizontal line slightly below the middle of the page. Draw the first tree line just above the horizontal line, using an unbroken squiggly line. For each building, use a ruler to make three straight vertical lines parallel to one another.
For the two buildings on the left, connect two of the lines with an inverted V shape. Then draw the roof as a slanted rectangle. For the barn on the right, connect two of the vertical lines with two angled lines as shown. Use two slanted rectangles for the roof.
