I've been taking the Electric Quilt class by Lyric Kinard called Artist's Toolbox. I haven't done as many of the exercises as I wanted, but it got me going on some pieces that have been on my mind, so that is good. The exercises are there to spur me on in the future.
One idea is to extend the picture from a photo or a magazine. It really makes you look. I have a notebook that I've put black and white photos in, because they intrigue me-so graphic.
