Seems there is!! Without any hesitation, long-time email pal Bonnie living on the other side of the world to me, wrote and said she had all these Zentangle items just sitting waiting for someone to play with them, and they could be mine if I'd just say yes. They were packaged and on their way from the freezing U.S., to the searing east coast of Australia, in a heart-beat!
Zentangles? I went looking at, and saving websites, watched u-tube demonstrations, and thought perhaps I could do this (with a lot of practice); and I started mine in a specially assigned, notebook for tangles.
So yes, I have continued "practicing", mostly at the very end of a day; when the computer has been turned off, and it's nearing bedtime. I will continue often till quite late, totally absorbed and penning away with a Zentangle pattern.
It does command your complete focus on every pen-stroke, and for that very reason really, it is ideal "therapy" almost, to take your mind away from the every-day, and to ....another place. It happens right there on the Zentangle tile, or in a journal or note-book; whatever you choose to Zentangle in, and I equate it pretty much to sitting with a crossword puzzle, or reading a book in your own special time.
On Enthusiastic Artist blogsite by Margaret Bremner, is a tutorial for Lilypads, the basis on the first pattern for me to share here.
