Quilt University class, Playing with Lines and Shapes by Lily Kerns. The first assignment was to make a bunch of little sketches. There was a lot more to it than just drawing a bunch of sketches, but I think you should take the class if you want all the details. Part of the second assignment is to translate one of your sketches into fabric. Below is my original sketch. I enlarged it to standard paper size, printed it out and used it to make a pattern for the above quilt.
