In this revised and updated volume, Harrison gives instructions for using water-based media--this time adding watercolor techniques to the encyclopedic mix (alongside those for acrylics and gouache). In some 35 lessons, she covers the laying down of washes, working wet-in-wet, spattering, scumbling, and creating texture with salt. An able teacher and artist, trained at London's Guildford School of Art and the Royal Academy School of Painting, Harrison has produced a fine volume. However, it can't quite match the breadth and excitement of Zoltan Szabo's 70 Favorite Watercolor Techniques (LJ 5/15/98). Copyright 1999 Cahners Business Information.
