The process of making a mirror 2

Ok, so the glass cutting went pretty well, not weird cuts at all, which means the glass is very good quality. Excellent!
Next step, is to decide the colors I'll be using in the rest of the mosaic. I think it will be a mix of greens and blues, but not sure the order: what will be the ribbons and what the background. Here, I apply the scientific method of "trial and error":

Final decision (never so final) is to make the ribbons in blue, and the background in light green with some darker hints. I still plan to use some aquamarine in the ribbons...
