This design is available on a custom T shirt in my Poshmark closet. If you have a Poshmark account, look up @suburbannomad.

It actually only took me one school day because the dots are relatively large and less dense. I'm currently working on a pointillism mermaid using smaller, more dense dots (which means higher quality) and I finish an area about the size of the palm of my hand in a whole day.
