I just bought a new book called Drawing Lab for Mixed-Media Artists, by Carla Sonheim. This book is just plain fun. One of the exercises involves making quick little drawings of imaginary cats, and another suggests filling in similar sketches with doodling. So I tried drawing some cats, and later filled them with doodles similar to what I've been doing in my "Zentangle-inspired" work. Then (of course) I added some Photoshop Elements effects for extra fun. Here's one example-- this one must have been inspired by colors and costumes worn in India.
