In mosaics she says the problem is usually a choice/anomaly a few pieces back that was off, and it builds from there. It's a ripple effect. Go back and fix it at the source and the problem solves itself. Valuable information for doing a mosaic, thoughtful information next time I hit something "off" in my life.
One thing I love about stained glass is the ability to piece it together like a jigsaw puzzle, only I'm the one creating it which gives me control. Yes, I like to be the one in control of my life. That fits.
