These doodles are mostly for stress relief for me plus training my hand after the time of many wrist inflammations due to strain. They were made from 2016 to now.
When I begin such a doodle I have no plan. All I know is that it will follow some rules how the edges are connected and what angles are allowed. So the doodle would just grow like a crystal. As you can see they also may vary in symmetry and number of axes - which also might be broken sometimes in favour of other patterns. That's what I call them, "Muster" - German for "patterns".
I usually do these on 4-5mm squared paper. Some were made on a thin hexagon isometric 5mm grid or dot grid. Some are made colourfull by pencils including ones in neon and metallic, markers or just plain ink.
The drawings here are mostly posted in the “Post Your Best Stickman” thread started by @LizEF. (Yes, a lot of these aren't stick figure drawings!)
It appears that following an album in the FPN Image Gallery, without also independently following individual images, will not generate notifications when comments on the images are being posted. So, please excuse me if I fail to reply to a comment left against an image here; I may simply not be aware of it, as I don't automatically follow each item of content I post.
