The author of "My First Activity Book" (1990) makes an assortment of traditional holiday projects accessible to young crafters. Like others in the My First series, her oversize volume features excellent, eye-catching color photographs--of materials and tools as well as of the carefully sequenced directions. Wilkes doesn't include gifts, sticking mainly to Christmas trappings, such as greeting cards, tree and household decorations, and wrapping papers. She does, however, offer a few undertakings developed in the kitchen, among them a fetchingly decorated Christmas tree cake. With projects both useful and fun to make, her holiday roundup won't sit on the shelf for long.
