Storm at Sea is different - I don't have a picture of the wall hanging I made but an image is easy to find if you google. It is made with all straight seams but overall it gives the illusion of waviness.
My avatar is from Norah McMeeking's book Bella Bella with a slight change. It is based on a pattern she adapted from Italian mosaic floors.
