I had to put this away and not look at it for a while, as I wasn't content with the end result - it seemed too cluttered. However, I must remind myself, that the ocean floor and territory between sand and the surface has so much more going on than we see in a clean and orderly fish bowl - I had been looking at Anne's wonderful project and forgot that part of it. (She has now posted the finished fish bowl)
We must remind ourselves of environmental protection, as it would be a shame to lose this glorious "clutter" in the sea. I was astonished at the beautiful colors and at the variety of marine life, although I've studied it for many years. I hadn't really looked at the coral reefs closely.
I was correct in my original comment about making the spaces for the beads, representing bubbles, equidistant when I marked them. I would have put stitches to fill some of them in, but as I had worked the needle blending, it would have been a lot of trouble to figure out what to put where. The next best thing was to go ahead and put both sizes Sundance #250 clear beads, and stagger the placement - random.
With this project finished, I'm not sure what to do next - all out of ideas. Anyway, I have painting to do to keep me busy.
