I do my bit for recycling by using only recycled slate (which has often lived on roof tops) which I then bright back to life as vibrant wallart by painting my animals or birds on it. I love the way the paint works with the slate to really capture the essence of the creature i'm painting. And all my slates are sealed and varnished, so can be displayed in homes or gardens too.
(If I am succesful in this application, please can I have a space under the trees, so I'm on meds that make me .ore sensitive to light exposure).
