So one of the topics in calculus was revolving a curve (graph) about the x or y axis. It is sort of hard to explain something that is going to be 3d on a flat surface. So I used those old time decorations made out of honeycomb paper. When we were in Branson, I saw these cards made from this paper so I had to buy some and try it. No Deb I didn't try to figure out any equations for the curves. Back on October 30, I showed you Jim's idea. These are what the stamps were suppose to look like. The puffy acorn is on the inside of the card.
