I know the 13th December is a bit late to start making cards for Christmas, but I had to start some time.
Every year I say I will make them in the summer, but nothing changes.
I designed the card on a vector based design package. It is actually just made of four
broken lines that are repeated through 30o from the centre of the circle.
I gave the file to Pete Griffiths, who used his plotter to cut the shape out of vinyl.
After "weeding" the vinyl it was stuck onto a clean piece of copper. I sprayed the plate with
several layers of car spray then peeled off the rest of the vinyl.

The card as it looks when it is printed. I included the cranes as they would be impossible to avoid.
