CheeseBurger and Fries: To make lettuce one needs to use a lot of no color translucent and a touch of green. I had some left over Kiwi and I smeared a thin slice of it on a ceramic tile. Then I scraped it up with circular motions with the tip of the exacto knife to get that fluted edge. Pick it up with the tip of the knife and place it on the burger, don't touch these things, they are tacky and get all flattened and full of finger prints.
