What do I say about why I left my last job? - what worked for you?

I have an interview next week and I am unsure how to explain why I left my last job as a graphic designer. I also do not want to seem like a risk. What do you say?

If a company has been in the news for layoffs, you can mention that. Often the interviewer already knows.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
