I learned this new thing over the holidays and I just love doing it. Of course, like anything, I have to add my own bits, but that's just me!
You start with a random doodle which I make with my eyes closed, or I try to control it too much. LOL Then I smooth out the pattern and work in the ends. Next is to fill in the areas with different patterns and designs till it is all to your liking. I take it further and then color it in with my pencils.
Now I am beginning to do some frames around the original doodles.
I cheated on my first one and used a photo of my cat Jazzy. I just printed it in black and white, then traced the main areas from the back and filled them in. After that, I was braver and the rest were made from my own doodles.
Am adding a couple photos to give you an idea. Now I see these patterns everywhere. Especially in fabrics!!! It's really quite amazing.
