The trope of the loveable klutz is a classic — and we definitely love Klutz. (We've carried their products since THE KLUTZ BOOK OF KNOTS was published more than 30 years ago!) These book—based activity kits — book-tivities? — run the gamut from papercraft to juggling, fashion design to robotics. Informative, engaging and totally self-contained with all the necessary supplies, including simple instructions, Klutz books get kids results they’ll show with pride — every time.
