Before I start working with the glass, I lay out the pattern and mark each piece with the planned color to be used. In this case, white is unmarked, dark gray is colored in with a dark pencil, orange is colored orange, medium gray is marked with an “M” and light gray is marked with an “L”. I had to take my time doing this because the pattern is not symmetrical and the colors have quirky variations that are important to the overall look.
Now I’m working on coloring in a second copy of the pattern. One copy will be used to lay out the glass on top of as I progress through cutting the pieces while the other one will be cut up to use as guides for the individual pieces as I cut them.
