An embroidery hoop is a circular frame used to hold fabric taut while stitching. It typically consists of two rings, one that fits inside the other, allowing the fabric to be stretched securely. This tension helps prevent wrinkles and ensures precise stitching, making it easier for crafters to create detailed designs. Embroidery hoops come in various sizes and materials, including wood and plastic. They are commonly used in hand embroidery, cross-stitch, and other needlework projects. By keeping the fabric stable, an embroidery hoop enhances the overall quality of the finished piece, making it a valuable tool for both beginners and experienced artisans.
