Zentangle and Zendoodle from books, talks, YouTube and Quilting Arts magazine. But it was Donna Jean, the leader of Journal Quilt Connection who got me interested initially. This is one of her unfinished Zendoodle pieces begun on paper and transferred to cloth. Click to enlarge to see the beads and embroidery:
DJ is a friend who is a beader and a quilter and we get together for lunch and the hunt. The last exploration took us to Ryco Trim in Lincoln, RI where she got some trim for her journal quilt made from a Zentangle. Go to Suzanne McNeill's hyperlink above at YouTube to view the process or Google Zendoodle and Zentangle to see other videos so you can start Zendoodling in a sketchbook for work you want to turn into a quilt. DJ says that a light weight polyester batting is less tiring on the hands.
I plan to show the grandchildren how to ZenTangle/Zendoodle on paper, but adults can take it to really sophisticated levels. Get a book to get started!
