Fractured Glass 2: Step 1 - A triangle, a pencil and an eraser

I am often asked: "How do you begin?"  I started Fractured Glass 2 with one triangle, and was delighted to watch it grow, shrink, and change directions. While working in pencil, I sort out the corners and the places where the shapes meet or overlap.  My two tools are a General Pencil Kimberly Premium Graphite 6H drawing pencil and a Faber-Castell Dust-Free Vinyl eraser.
