These pieces of art were originally just practice, but I ended up liking them so much that I decided to make some cards with them.
The base colours are dylusion ink sprays which I muted by adding white gesso when the ink had dried.
By using different colours on various areas of an A4 sheet of card I managed to get 4 postcard size pieces of art that all co-ordinate.
Once my base of Dylusions and gesso had dried, I added some black acrylic paint and then used my white Sharpie pen to add the graffiti.
I really love the overall grunge look.
