This instructor's guide provides an overview of 4-H student project modules in the textile sciences area. The guide includes short notes explaining how to use the project modules, a flowchart chart showing how the project areas are sequenced, a synopsis of the design and content of the modules, and some program planning tips. For each of the project modules the guide provides information on the skills and concepts taught and ideas for projects. Resources also are suggested. The textile science project modules cover the following topics: beginning areas (sew much fun, stitch by stitch, and sew much more); intermediate projects (knits, coordinates, accessories, sewing for other projects and people, time-saving sewing, and creating your own project); advanced (tailoring and formalwear); creative (design, closet connections, wardrobe planning, and clothes shopping); and textile arts (weaving, knitting, and crocheting).
