Finally, I have a concept worked up. I tried something, and it didn't quite fit the rules, but I made a bunch of them because I liked them. I tried something else, but it was just going to be too finicky to make with punches ... but I WILL be making it, becuase I love the idea. And then, today , it all came together. This is the first one.
All the cutting is punches, except for the straight parts of the card outline (which is paper cutter), and also I cut the side raised rings in half with scissors.
All the images: vitruvian man, mona lisa, flower of life design, foetus, are from Leonardo daVinci.
Now ... to make three (or more!) more!
