In this lesson, "Ice Skates on a Log Cabin Wall", Ginger shows you how to take a smaller "sketch" painting, 6x8, and using the grid system to enlarge it to a 9x12.
The website used for the griding isĀ griddrawingtool.com/. There will be a tutorial from Sammy and the team shortly. In the meantime, there is a grided version under the Resource tab.
