In this exclusive real-time tutorial, I demonstrate how to use a proportional divider (scale divider) alongside the grid method to create accurate outlines for a large horse drawing. You’ll see a simple practice example first, learning how to transfer shapes and proportions by adjusting the divider and marking points on your drawing sheet. Then I apply the technique to a full 65×92 cm sheet of premium 350 GSM paper, setting up a 7×5 grid to scale the horse reference properly. I also share the pros and cons of the divider—why a thinner, sharper model works better—and how combining it with the grid method saves time while improving freehand accuracy. This tutorial emphasizes precision in the outlining stage, so you avoid major mistakes later during shading. References, including the outline grid, are provided in the Materials section. The second part of this horse drawing series will cover shading in detail.
