One of the things I like about art is you can use anything it's so creative, I saw a landscape at an exhibition I went to years ago it was incredible and it was made with vegetables set in resin .
I will give anything a go, I did a picture of a rose years ago out of veneers stained and burnt to get the shading (that's actually hung in my nans house in pride of place above the fireplace, don't know what happened to it when she passed on though)
