This is https://www.spoonflower.com/designs/9833604-aqua-blue-lime-green-faux-shibori-on-navy-blue-by-gargoylesentry Designed on my iPad using Procreate software. Please contact me if you’d like to see this design in a different scale or with a different repeat design. I used a half-drop repeat because I like the green spirals not to be all in a row.
