Seashell Pinwheels

Isn't this georgous?!  I don't know the name of the block but it is made with strips and has that bias rolled back edge like the 10 minute block.  No actual curved piecing.  The fabrics are so pretty and the backing...love!   King sized and as pretty as it is, I sure was happy to reach that last row.   I stitched a swirl design that resembles a seashell in that space and created a feathery design to fit the black irregular units.
