What is the "rule" for quilt borders?
I'm making a king size quilt, and have the center of it finished. I would like to add borders, but they would start at the sides and hang down. Is there a rule of ratios that I should keep in mind? I would like to use 3 different fabrics, light, medium, and dark for the borders.
Usually, I make scrappy quilts, and don't make borders. Can anyone help me with this?
