Cyanotype Workshops

I have dates for workshops in the Devon Open Studios Brochure. I failed at proof reading as the 18 September is there twice as a Lampshade workshop date , which should read 17 September . The Cyanotype Workshop 10- 13 on 18 September is correct also 11 September 10-13 also, with World Cyanotype Celebration workshops on Sunday 22 September, booking with me
