This is a paint pour - acrylic paint mixed with Floetrol, poured in various color layers into a plastic cup and dumped over a canvas. There's a bit more to it than that, but that's the gist. If you're interested in learning more, there are a lot of online tutorials or you can check out this book Paint Pouring: Mastering Fluid Art by Rick Cheadle. I did a few experiments on small inexpensive canvases and below is how one of them turned out:
I uploaded this photo to Procreate on my iPad and played with it, adding a bit more black and a few highlights, etc. to get the image at the top. I'm wanting to experiment with more and possibly incorporate these beautiful designs into my illustrations!
This is the kind of messy project I want to do in my studio, not the dining room table. I've been waiting for my basement studio to dry out from all the rain, but it's been damp with rain puddles down there for months. I may have to go get myself a pair of rain boots and just do it.
One more thing before I go, something I want to put out into the universe - I finished a manuscript yesterday for a middle grade novel!!!! I don't have co-worker authors to give me a high five. My phone didn't automatically ring with publishers and agents begging my attention. No big check appeared in my mailbox. But, I did it! Yay!!!
