Sorry about the cardboard; this is just a documentary shot of today's cyanotype experiments. I'm a happy camper. Such fun to see them come to life in a pan of water! :)
@juliedduncan Thanks - I have just used some cheap watercolour pad paper but prefer less textured paper. It has also been very overcast here today so my exposures have been 20+ minutes. I think there is a lot of info online however the book looks really detailed and has good reviews. I have considered it.
