SO, when the Sarasota Surface Design Guild posted that they wanted members to bring in decorated work shirts or aprons, I decided to make the leap.
For this project, I washed an apron bought at Hobby Lobby. While it was still wet, I did a watercolor wash. Then, ironed it dry, and used "Stained" fabric markers form Sharpie to draw the pen at the top, and to tangle the center and border. It was easier than I thought it would be!
I'm pretty happy with it, and am now searching the house for other surfaces to tangle!
