@ethelperry honestly it is quite a simple method and something you could easily do at home on your deck. i painted the chemical myself onto paper, but you can buy pre-coated fabric here https://www.eckersleys.com.au/jacquard-cyanotype, then it is a matter of arranging some objects on top, perhaps pressed leaves and flowers if you want crisp edges, but i also used objects and fresh foliage as in this one, i have a small piece of glass out of a picture frame i used to keep everything in place. these were left in the full sun for about 5-7 minutes for my paper ones. fabric ones could then be used in patchwork or other textile projects, i will try coating some fabric too this summer to see if i can get it happening.
Excellent work!
