If you're using a light-colored fabric, you may be able to trace directly on the fabric. In this case, I'm using a very opaque canvas fabric, so I had to first trace the design on paper, directly from my computer screen.
Don't use a drawing implement that requires too much pressure or that will bleed through onto your monitor. A regular ballpoint pen works just fine.
