It's super quick, inexpensive, and easy!
Step 1: Step 1: Create a design for the stencil
First, you need to design your stencil in Illustrator. I wanted to make something that would make people smile on the street so I chose nice sayings, like a love poem to the city. But, really anything and everything is possible!
Just make sure to outline the text (Ctrl+Shift+O on a PC) and set the stroke to .001 pt so the laser cuts through your outline.
NOTE: I'd like to mention that if you do not have a laser cutter, you can simply print your design, lay it on top of a piece of cardboard, and use a blade to cut it out. This method will take more time and will not be as precise as a laser, but it's definitely still doable!
