Q: I DON T UNDERSTAND HOW TO MAKE THEM!
A: Follow the instructions on the top page, but also take a look at the
following diagrams:
1. Make curved scratches as shown above
Your first hologram should be something very simple. How about the letter V.
First draw the little V as a guide. Draw it near the bottom edge of
your piece of plastic. Next, use the dividers to make lots of curved
scratches above the V . For each scratch, place the point on a different
spot on the V. Each scratch should be a quarter-arc or even a
half-circle. Don t change the distance between the metal points.
