Step 3: Start Gluing Tiles
Apply Glue: First, apply contact glue to a few of your mirror strips, then in a few inch band around the widest circumference of your helmet as shown hatched in red. The mirror strips will take longer to dry because of the porous fabric. Wait until both are dry to place your tiles. Upon contact of the two surfaces, there is not much ability to reposition. If you want to play with how your tiles will look, do so before applying glue.
Align Your First Row: They key to making your helmet look awesome is to make sure that your first row of mirror tiles are well placed. I wanted the tiles to lay flat against the rim of the helmet in front, and used this as a guideline for the angle of the first row of tiles. If I started with them against the front rim and continued this line straight back, it follows the largest circumference of the helmet and ends about an inch up from the back rim of the helmet.
Glue Mirrors in Back: As the angle of the first row left an inch in back and I wanted things to be exact, I started by gluing two small rows of mirror in back to serve as a guideline for when I placed my first row.
Place Your First Row: Now that you have the rim in front and mirrors in back as guides, carefully place the first row of tiles around the entire helmet, taking care both sides are symmetrical. All the tiles will be based on this row, so this is the most important part!
