Knitting patterns are instructions that guide knitters in creating specific designs or items, such as sweaters, scarves, or blankets. These patterns typically include details about the materials needed, such as yarn type and needle size, as well as step-by-step directions for each stitch and row. Patterns can vary in complexity, catering to beginners or advanced knitters. They often feature diagrams or charts to illustrate the design visually. Many knitters also share their own patterns online, contributing to a vast community of crafters who enjoy knitting as a hobby.
