In one of our classes we learned how to use a laser! Our teacher gave us leather Christmas tree ornaments that we could create a design for and then laser engrave the design onto. I made a Christmas tree design with my last name on it to hang on my Christmas tree. We created the designs in Illustrator, and then transferred them onto another computer connected to the laser. You have to watch your stroke weight though; a stroke of 0.001 will have the laser cut the material.
When I tried to laser my ornament, the design was super off and not centered. My teacher and I were not sure why since the ornament matched the paper. I redid it and tried again on the back but it still did not laser the design in the center like it should have. My teacher then lasered out the shape of a new ornament into some wood so that my ornament would be perfectly alligned. We tried that and it worked! It was cool to watch the laser work and have an ornament with my design engraved into it.
