I will never look at wall paper in the same way again!
And I really now appreciate how hard those Victorian pattern specialists must have worked, because I have been cheating a bit (with a modern hewlett packard printer!!)
I have been using the 'tiles' that I created a while ago, photocopied them (a few times) and then cut them up and stuck them down to create slightly different repeat patterns.
Then, using tracing paper, I have traced images to make them stand alone and to get a feeling for how they might look.
I am quite please with some of the results, which I think I might develop further as Thermofax screens.
