Crewel embroidery is a type of hand embroidery that uses wool yarn to create intricate designs on fabric. This technique often features floral and nature-inspired patterns, allowing for a rich texture and vibrant colors. The stitches used in crewel work can vary, but they typically include back stitch, chain stitch, and French knots. Originating in the Middle Ages, crewel embroidery was popular in Europe, particularly in England. Traditionally, it was used to decorate household items like curtains and bed linens. Today, it remains a beloved craft, with both traditional and modern interpretations being created by artisans worldwide.
