The Roll & Press is a convenient and quick way to press seams at the sewing machine. Roll to press a seam or fold. Straight, curved, or paper pieced seams. It won't pull or distort fabric; the wheel is tapered to focus pressure on the seam. Comfortable, ergonomic handle. Perfect for paper-piecing or laminates; also use to seal glued seams on leather and felt. Such a great seam roller!
