Step 2: Prep Mirrors and Helmet
Cut your mirror tile fabric into strips. I alternated between a knife and scissors to do this.
If your helmet has snaps for a visor, you will need to remove them. I did this with a jeweler's saw, however you might be able to pry them off, or remove some other way if you don't have a jeweler's saw lying around. Better yet, find a helmet without snaps.
