The Radstock Museum itself is well worth a visit. It covers the "social and industrial heritage of the communities of the Somerset Coalfield". Also a good place to leave someone not interested in quilts.
As I said above, you can visit the virtual gallery on the MQ website, I just would like to show you some of the quilts I liked or found interesting.
The exhibiton is open until 31st May'12, plenty of time to visit.
I finish this post by another quote from the exhibition guide:
"Last year a study carried out at Glasgow University concluded that quilting, more than any other craft or a pastime, was hugely beneficial to health and well-being (but we knew that, anyway)."
Happy stitching!
