The next wave is nearer, hence larger. First I sewed on the lace...
....folded the sea....
....and fastened the sea slightly behind the top of the wave.
To give the wave a round shape I embroidered a line of stem stitches just below the foam.
Later I will add more embroidery.
The sea so far. Of course the front wave rolls over the beach.
