“The lines are the mathematical structure on which the artistic effect is built”

If we take the concept of line as route between locations as shown in the previous post, now let’s examine the reverse situation of adding length.

We begin the same way, defining the start and end of the route where the vertical distance will be added.

We then pick a position somewhere along the route and add the required extra. For convenience, we will use the same value, adding 5½ inches (14 cm).

Now we need to draw a new line, the adjusted line.

Enter the ruler.

A ruler is a handy tool. Rulers are templates where the edge of the ruler is used as a template for drawing a new line.

The original line now provides the template to help make the new line. In essence it is the outside edge of the pattern piece but we can think of it as analogous to a ruler. The route is now a ruler.

With this ruler, we now can draw the adjusted line in stages, blending from the starting point to the destination.

The new route has been determined.

The outcome shows how the pattern has been adjusted with additional length with a single alteration.

And, in case you were wondering, we could have chosen another position along the route to add our extra length and the outcome would be the same.

You are a brilliant teacher.
