I finished this tonight! I did another Smyrna Cross Combination in the bottom center with the Kreinik braid and then did a buttonhole stitch around the outside with Petite Frosty Rays. I also did the basketweave to fill in the rest of the background. The directions call for a couched thread half way around the buttonhole stitch, but I did not like how it looked, and took it all out! The subtle blue shades in the white background balance the heavy dark on the left. It really could be water washing up on the beach!
