What is...?

I added a "What is...?" paragraph to my website. What is scratchboard? I'm asked that question a lot and thought I'd finally put a little blurb in explaining it before viewing my actual scratchboard examples. I used the easy approach, wikipedia, and got a nice quick sum up.

I hope to one day write a more in depth, with pictures, more personal, 'What is...?" when I have the time.
