Karen was working on this at our guild retreat last fall.  It's paper pieced and I enjoyed watching her work through the process.  Lots of patience there :)  The colors are fabulous and all the fabrics work perfectly together.  It's 60 x 60.  I used 17 different threads . . .
I quilted pebbles behind the spikes in the cheddar sections and also in the bright yellow spots to help those spikes stand out:
The central star got line dancing with loops in the middle of each side of the diamonds:
I love the multi-colored fabric that borders the star and pulls all the colors together.  I used a variegated thread that has all those colors in it, and just followed the waviness of the fabric:
I put reversed "C's" in the black border:
I used wavy lines on the seam lines and in the middle of each cheddar border piece.  I can't believe all the different cheddar fabrics that are in there . . 
The back is a black/white paisley print:
