How do you sketch out your (day)dreams?

I may be wrong, but I think that many of us permies spend a lot of our time in-between tasks thinking about wonderful possibilities.

I flip flop between writing my ideas in a notebook, sketching ideas on graph paper, and pulling together inspirational images from the internet.

I find that writing things in my journal gives me the best ability to reflect back on my thoughts and how they changed over time. I'm not much of a sketch artist, but when I start to have concrete plans for something I find I can't really figure it out until I measure and draw to scale. And I'm certainly not an innovator when it comes to building or making things, but I do often combine ideas to build what suits my needs. So printing multiple pictures of an object I need (like a shaving horse) lets me figure out how to make one with what I have.
