Now I'm curious - what are you envisioning? I think of most quilts as being geometric, involving a lot of straight lines. Are there traditionally-pieced quilts that give the look you have in mind? I use a lot more shapes in EPP than in traditional piecing (which is mostly squares, rectangles and triangles, with the occasional 60 degree diamond on a wild day).
If I understood better what you were looking for, I might be able to point you in a more helpful direction.
