I hope that my friends and I have been able to encourage you to try your pen at Zentangles. I do it for the relaxation and to help me with my machine quilting. It's working. I do find it hard to fit everything into my day, but it's worth the effort. Even a few minutes spent doing a tangle helps to relax me. If you've been thinking of giving it a try, please do, you might surprise your self and find it enjoyable. ps, it's also something you can do with your kids and/or grandkids.
Mr. Linky is waiting below for a link to your Zentangle post.
