Two ""Once Upon a Touch"" books, with textured inserts, pull tabs, liftable flaps, etc. The hat book is marginally the more satisfactory, featuring a dozen familiar favorites--hats for chef, policeman, astronaut, and magician (this one yields a rabbit). But the story of a beloved blanket gone missing has nothing new to offer on this well-worn subject; instead, try Jonas' new Where Can It Be? for a delightful rendition (p. 1446). Both texts here are in clumsy doggerel; illustrations are bold and colorful but undistinguished. Children will enjoy opening the doors and feeling the fabrics, but the most entertaining effects are also the most fragile. More toys than books, these are not practical for library purchase.
