Here's a 4 tile ensemble that is being done as a challenge by my "Zentangle Reunion" group here at Hawthorne Park in FL. You can buy pre-strung ensembles from zentangle.com but you can also just make your own. I decided on 4 rather than 9 as we are a small group and it's our first try at this.
My handout has a black line drawing of the string that you have to trace on to your tiles yourself with a pencil. Number the backs 1-4 and put your name and your tangle names on the back and bring back to the group to be re-assembled...but this time with 4 different tiles not your own. Voila. A whole new ensemble! I encourage folks to take a photo of their own ensemble before they turn it in at the group meeting for shuffling.
Our deadline is Feb 3 so I have to keep tangling. You'll see I tried Maria's new Aquafleur tangle in #2. It's so beautiful and the possibilities are limitless which makes it a terrific tangle!
