Here is some of my play with Tripoli.
For the first tile I used Zentangle's basic 'triangle' string. (It's sideways now.)
I had a tile with an 'R' string so I used that next. (It's upside down now.)
Then I pulled out a bookmark-in-waiting with some old art on it. Nice colors, and the original art had a bit of a square grid so that was a little challenge.
As always, thanks Laura the Diva CZT!
