For my mom's floral quilt, I did a 1.5" green border and then a 4 or 5 inch blue border because it's her favorite color. The blue also complimented all the floral fabric in the quilt. If I were do remake that quilt, I probably would have done just the 1 border, in the green, but at 3 or 3.5 inches. She loved the quilt so all is good.
