If you hit my spoonflower site or Image Catalog (or Pattern catalog, now all mobile-friendly), you will notice lots of dizzying fish and dolphin patterns emerging...why may you ask? Because I did those two adult coloring books (now on Amazon, bn, etc.) :

Of Oceans and Rivers, Fishes and Whales: A Coloring Book of Marine Life for Grown-ups and other Children (available on Amazon here)

Of Oceans and Rivers, Fishes and Whales II: A Coloring Book of Marine Life Patterns for Grown-ups and Others (available on Amazon here)

In doing those two books, especially the second one (which is all patterns, black and white of course so you can add your own imaginative colors), I got inspired to make the natural full color patterns for stuff and fabrics/wrap/wallpaper too. 

What emerged are flowers, stars, swirls, wheels, and the like...which I hope you will like.

I might make a few into cool Hawaiian shirts for myself :0)

Calm Seas, Sunny Shores, and Tight lines,
