I also enjoyed using the tangle Athitzi by Seven in my tile for the Diva's weekly challenge. Athitzi has a textural feel that reminds me of the drawing style hatching. I used this technique to create shading on some of the other tangles that I had used such as Dragonair by Norma Burnell. I also incorporated the tangle Akoya by SandyHunter into my tile by drawing it around Meringue.
I used a regular No. 2 pencil and black Micron pens in various sizes for shading. I really liked how the shading and hatching technique added dimension in my work. Now, I wished I had scanned in my tile before I had applied shading so I could of posted a "before" and "after" image of how shading makes a difference in one's art.
