Way cool quilt. Could this style also be done in a paper piecing method? (I have only done one small block paper piecing so I really have no idea.)

I don't think so. There's no way to get a curved line with paper piecing, as far as I know. You could try a sample and see.

I haven't done anything like this quilt. But this idea came to mind when I saw the picture. Seems like I've read about it somewhere....

Stack up several large squares of different fabrics.
Cut a curvy line through all layers.
Put the top slice from the first fabric on the bottom on the stack.
Cut another curvy line through the whole stack and repeat the process of moving one slice.
Repeat as desired.

Of course, the squares get smaller as the pieces are sewn back together. I have NO idea how to figure out what starting sizes result in what completed sizes! Guess it might take some experimenting!

Maybe this won't work, but I can't figure out why not.

Sue, I think that works as long as the curves are very gentle. The problem with this technique is that there are no seam allowances, so overlapping curves far enough to sew together can become a problem unless the curves are very gentle.

Oops - Just wanted to let you know that Jean Wells has a technique that is very simple to apply to this type of block construction - whether free form or blocks or not. Her waving and gentle curves and method are easy as I recall. I can't remember the name of her quilt shop in Bend, Oregon but she has published numerous books for Patchwork Quilts books. I saw her demonstration on the PBS show called Quilting Arts. I think her easy method of construction would work perfectly for you. Best of luck.
