I have only seen KF books, never individual patterns.
There is a pattern that might work in Judy Hopkins' book, Triangle Free Quilts (pub. That Patchwork Place, 2002). You sew assorted width strips together into units, then cut widths of 6, 4, 3 1/2, and 2 1/2 inches from half of them, and 8, 5 1/2, and 4 inches from the other half.
The quilt alternates long bars of these six widths with assorted width bands of a coordinating fabric, then puts a couple more pieced bands above and below, and adds a border of the coordinate.
