Perfect, thank you! I work in Oakland and am down that way about once a week!

And thanks Jim that's a good idea, I'll keep my eyes open for orange or yellow. I cut the window with a mat cutter and it's the edge of the image on the bevel that would be most helpful to see, so in my case it will be the top mat. ( Not sure my post was clear... I've been using black-core flat black mat board. )
