The PDF of the ad was placed in Illustrator. Then everything (type, logos,stuff) was deleted, except for the comp of the house and tape measure. The sketch of the house was then scaled up to about 2.5 times larger than the final print size and then made into a template dimmed to about 60 percent. Even though this is being done on the computer, I still work 2 to 3 time larger than the final print size because I always want the option of being able to print the image out on a piece of scratchboard, and finishing by hand if needed. This illustration ended up being drawn completely in the computer, but many times only part of the illustration can be handled with the computer. In that case, it is printed out at that stage on to a piece of scratchboard, and finished just like a regular scratchboard illustration.

Be warned though, running scratchboard through a printer could void the warranty (scratchboard has a thin clay coating which could come of in the printer).
