Multicolored sgraffito bowl

If you received a homemade card from me within the last few years, the chances are very good that it was distressed. That was my favorite technique when rubber-stamping. What is this distressing technique? It's either rubbing off the edges or adding ink to make it look old or worn...antique-like. Well, I kind of combined my favorite technique from pottery (sgraffito) and my favorite technique from paper arts (distressing) on this bowl. Even though it has shiny glaze, I rubbed off the black slip on the edges to give it some more character.
