I decided to do my wife a nice A4 framed line art picture of our cat. The feedback has been brilliant and I have requests for others. I use the layer with the guide line to cut the framing piece too, in black. If you use the plywood you can use both sides so there are options as to which image to display! The process I used was, take a photo, edit the image to isolate the face. I then processed the image into line art online and tweaked in Inkscape until I was happy with it.
