Provide any custom image.
Thin line, black and white, .svg's will plot best.
Any image can be converted but an image with thick lines will convert those thicker lines into an outer and inner line. This means there will be two lines instead of one large one. The example image shows this.
The image will be plotted to fit fully on a piece of 8.5"x11" ( ~ 21 x 27cm ) card stock.
There will be a small margin to allow for cutting to fit into frames that aren't a perfect 8.5 by 11.
