Does cotton grow on a tree? What does a butterfly have to do with a silk scarf? Are knots just for sailors? With colorful and richly illustrated materials, children are on the trail of the secrets of fibers. They discover where animal and plant textile raw materials come from, how they are obtained and processed. Four projects provide solid factual knowledge and inspire creative design. Students learn about various raw materials through experimentation and sensory experiences, which they then turn into small projects: they spin and weave, felt and sew, braid, knot, and crochet. Silk is painted in vibrant colors using different techniques, and cotton fabric is printed in original ways. All instructions are presented in such a motivating manner that boys also enjoy textile design. From fiber to yarn, from fabric to textile.
