There are lots of good things in the Red House, Bexleyheath where Jane and William Morris lived after their marriage, including two sets of stained glass windows that seem to have been shoved together in the patchwork style at a later period. This internal glazed door with scratched signatures, including May Morris', looked very beautiful in the space.
I am thinking of doing something similar with visitors to Kelmscott who would like to leave their mark on a piece of glass.
One visitor this week told me the interesting story of "The Moving Church" in Biggin Hill. This was built in the 1950s by the Vicar, Vivian Symons, from a quite different church in Peckham and he engraved the windows himself with a dentist's drill. Are there any pictures of them out there?
