I took an online Craftsy class from Carol Ann Waugh called Stupendous Stitching and learned several simple French Knot, Running Stitch, etc. Her class is fabulous and so is she!
Taking Carol Ann Waugh's class was a turning point for me. I used to sew everything in ivory, beige, and blah. After taking Waugh's class I'm creating in LIVING COLOR. It is so exciting. I highly recommend signing up for her class on Craftsy.com
