Have you visited the workshop section of the Passion for Promarkers blog? It is definitely worth a visit. I have downloaded a few of the workshops and used the Sepia one by Caryn to colour these two Willow images from the Whiff of Joy City Girl collection. I can't tell you how pleased I am with the outcome.
