The Blues

I was going through some art pieces and came across my blue scratch pieces. It has been awhile since doing that kind of process. Looking at them got me all inspired but I am working a piece with different materials and a different process. I have a question for those of you that like to make art with different styles, materials, and processes. 

How do you keep the inspiration alive when you want to do one thing and you're working on something else? 

If you do commissions, when do you find time to do your own pieces?

Can you work on two different styles or techniques at the same time?
