When Paula had the first show at the American Folk Art museum in 2009, there were also some videos up on their site with Paula taking the viewer through the exhibit.
I couldn't find these on the museum site anymore but remembered that Gloria Hanson had posted them on her blog back then.
So if you can't get to actually see them in person, this will get you closer:
