I've mostly been doing traditional Zentangle art--black on a white tile. At my CZT training, I started to play with some variations with surprising results. I started these tiles at the training but didn't finish them until yesterday.
Here's my first white on black tile. I absolutely love the shading and highlighting effect the Gelly Roll pen has, although I missed the feel of the Micron. I didn't think the lines were as sharp, but the pen was also a bit more forgiving in that the first stroke was often lighter.
Next I played with my green Micron on a white tile. This had some fun effects too especially once I shaded. I think Fengle is going to be one of my new favorite tangles!
Ok, this one isn't a different color, but it was also started during my training and finished when I got home. I learned Betweed at the training and love how Mooka fit right into the center ribs so it looks like the fronds just curl right from the center.
