Durable spring loaded clips hold fabrics securely, quickly and easily. A great alternative to pins when working with thick quilts, heavier weighted fabrics, vinyl or piled fabrics. A must have tool for holding sewing projects with layers; i.e. quilts, handles, piping, bias strips, etc. Clips are quick and easy to remove when sewing or serging. The semi-transparent colour makes it easy to see through to the fabric.
