Tricia has been my swap partner several times and last time she surprised me with a collaborative zentangle. I liked the idea very much, so I sent her one too! Her zentangle is 5½ x 6½ inch (about 14 x 17 cm), mine is 4 x 4 inch (about 10 x 10 cm).Today I finished Tricia’s zentangle. I used my Sakura Pigma micron pens in 3 and 5 mm. It was fun to work on, thank you Tricia!
