The above postcard has some dyed cheesecloth to simulate water and several commercial cottons as background mountains.
This postcard was inspired by a technique from Gloria Loughman's book, Radiant Landscapes. I used a copy-write free image of a palm tree in the front, and my rusted fabrics as the background.
I'll post some others, as I send them out; I don't want to share them here until I've sent them to the birthday people.
