Have you heard. They now have coloring books for adults. I love to color when the designs are like Zens. You know Zendoodle, Zentangle. Here is one I have done. Not coloring pages, but Zens. I love to do Zentangles.
Now the coloring books. Have you heard about
I just placed an order for the first and second book. Reminds me of when I was in Middle school and we had Folders we could buy from the school store with hidden animals and such we could color. There is other books by other companies also. Go take a peak.
