Step 6: Finishing the Bottom

Finishing the bottom is the most time consuming part.  If you are not a perfectionist, you can continue adding rows like on the top, fit as many squares as possible before reaching the rim, and call it a day.  However this leaves an imperfect edge, and I wanted a clean edge. 

In order to fill in the gaps, I marked the mirror with a sharpie, and used a glass cutter and large pliers to cut the squares to shape.  Ideally one should use a proper breaker as the pliers I had sometimes shattered the glass, but it was what I had on hand. 

Cutting such small squares is difficult.  Have patience.  You will get better at it by the end of the helmet!  And be sure to reuse pieces.  Often the discarded half of one piece was a perfect fit for another empty space on the helmet.

Unless you're quite tall, it might have been nice to finish the top using a similar technique.
