I'm trying to make interesting patinas in plaster models covered with copper sulfides or copper powders, and this is just fascinating to me! I'm also investigating different variations, but your longevity at this is quite impressive!
Hello Astraea, I've not tried dried flowers, but I don't see why not... I've used tea - which is dried organic materials and they offered up some lovely patinas.... give it a go and let me know how it went. Nicole.
