I decided that since I was drawing mandalas I should try drawing one on fabric. I have several tote bags I dyed a few years ago and thought they would make a good foundation for the mandalas. The first line I made with a Posca pen wasn't as refined as the mandalas I've been drawing on paper. I decided to see if the Pitt pens, which are India ink, would draw on the fabric. They did! And they made beautiful lines on top of the Posca paint! The mandala itself is about 6" in diameter. I decided to seal/set the paint with Golden Fabric medium, GAC-900 and ended up with some staining over my signature. I will wash it and see if the staining fades. I doubt it, but one never knows. I decided I probably didn't need to do anything more than iron the fabric to set it. Live and learn. When the bag is filled, the design doesn't seem as small but I didn't try this until after I drew on more bags. Since the 6" size felt small at first, I decided to size up to an 8"
