Wavy Feathers

What do people quilt on top of applique blocks?  Deciding what design to quilt was difficult since these applique pieces are quite large.  I didn't think edge stitching alone would look right with this size, so I finally decided to go with heavy quilting within the applique itself.

The center, below, is a simple continuous line motif.  It's a little wobbly, but that's okay. 

Here's a shot of the back.

I think I might need to name this quilt "the tortoise" since it's taking so long to finish.  Oh well, slow and steady.
