Have you tried flow painting yet? You must! It's so much fun! Every canvas is a surprise and it's mesmerizing to watch the paints react with each other. I'm obsessed.
Here is one of my first canvases:
Look at all the gorgeous cells in this one!
There are so many recipes and how to's online. You'll have a blast watching...just like I did. I know you will. Try flow painting with your kiddos, too. They'll love the combination of science + art.
I have been happy with this combo:
1 part acrylic paint
1 part Floetrol and Liquitex Pouring Medium
1 Part water
Then I top of the each color with a small squirt of silicone.
AMAZING results! You can see videos of this process on my Instagram and and an 18 minute how to on my Facebook timeline.
Go try it!
