The pictures below show the chenille sun in a horse quilt. Concentric circles were used.
Using the Circle Lord you can make concentric circles, spirals, diagonals,
curved diagonals from the Curved Crosshatch and some of
the Aztec patterns -eg scallops. You could even use the Waves part
of the Zig Zag template by moving it up 1/4 " at a time.
Below is a picture of a test piece by Marcia Stevens using the
Spirals template and diagonal lines
Just some ideas.
Cheers,
Michael
