This is today's tangle - I call it Urchins because those little guys in the middle remind me of urchins.
I also thought I would show you my ideas journal. It is a Moleskin drawing pad and I have divided the page up into 8 sections. I keep a different idea in each section. The book currently has hundreds of designs - both mine and those I have borrowed from others, but mostly mine.
As you can see, some are simple and others are a bit more complex. It is a really good way to keep ideas and use those ideas for future drawings. You can always find ways of adapting any idea into a pattern.
