Side note: Intended fabric size of this design is a 2.0 x 3.77 repeat. It was enlarged for the Barrier Reef contest to show the detail in fat quarter scale. Because this is hand drawn and not some kind of vector or other computer generated graphic, it looks much better in print, in the scale it was drawn in, or smaller, rather than the 5.27 x 9.93 scale you see here. I will be putting it back in a smaller scale when the voting ends.
