I have some patterns that I've never posted because I felt they needed too much attention to keeping things straight and in proportion. These patterns are still Zentangle®-inspired, but I'm not sure they would be considered tangle patterns. Some are easier to do if you pencil lines in as guides (even on grid paper). I think they will stimulate rather than relax. With some of them, you will get a visual effect. For instance, if you stare at the pattern below, Pywakit, you may see a white glow around it, and the white areas may seem to pulse.
The Rhodia Journal Swap is being done in Webnotebooks. Each page has very light gray dots. They are dark enough to help guide the eye, but few people notice them once something is written in or drawn in. Do you see where I'm going with this, lol? The patterns I'll be posting for this round of the swap can be done freehand, but will be easier if done with a dotgrid or graph paper.
In other words, patterns perfect for Webnotebook.
There are 12 of us in the Rhodia Journal Swap. See what the others are doing in their Webnotebooks.
