A trick I learned from a friend is to take a bunch of the color thread you think you want to use, let it bundle up on top of the quilt across most of the colors and step back. Do that with each of three colors you want. Decide which one you like best and be fearless. Remember, almost no one will be looking at it as close as you will. I just took the spool and unrolled a bunch of each color in a section and stepped back. Why she said only three tops is it's too easy to get frozen with indecision. Good luck.
