Coloring books for adults

I featured this book in my "GENIUS way to start watercolor painting EASILY" video. I own four books from this collection and they're all beautiful.

This is the one I own. There are many other art brands offering this type of product, however. I've used this to prime my coloring books for watercolor and heavier use of water than normal for coloring book paper.

This is not the one I own, but it's similar. Make sure to check the size of this one fits the size of your projects before purchasing. I use this to apply my primers on non watercolor paper surfaces that i'll watercolor on. I like that I end up with a smooth surface, no streaks.

Another one in the series with the cutest designs. I have used it in a gouache painting video on my YouTube channel.
