I am making a postage stamp quilt and need help with the border. The squares are 1". I am making this quilt for a couch throw and would like to make the border approx. 6" wide. I was thinking about having a small blue 2" border around it first and then a larger white (eggshell) border around that. Really don't know what color to use since all of the squares have so many different colors. Help!!
