I was having difficulty with my sewing machine while free-motion quilting. I sandwiched a couple layers of white cotton fabric and Hobbs batting, threaded my machine with black thread and began stitching whatever path I chose. I meandered all over, sometimes drawing and sometimes writing, all with stitch. Eventually the machine tension was corrected and I ended up with a neat black and white piece. I thought it looked pretty neat, but then gave it to my sister to add a little colour. Wow, what a difference a few colourful fabric markers make.
This one was just playing around with shapes using a black Sharpie pen on white fabric. Some colour was added, and voila!
