First, you will want to enlarge your image to fit the size of the mosaic you want. I'm going to be creating a mosaic that is 5 feet wide and roughly 6 feet tall and arched at the top. My mosaic is going to be of a downtown scene. It's way more affordable to enlarge to this size in black and white and I'm really only using the image as a guide. Tape the enlargement down and cover it with clear plastic like so.
