This sewing assisting tool can replace the hard-to-find Jean-A-Ma-Jig. When sewing thick materials, placing it under the presser foot can help maintain the stability of the presser foot during stitching, effectively avoiding problems such as needle skipping and needle breakage. This special model is particularly suitable for sewing thick knit fabrics and lightweight denim, and it performs especially well when hemming the bottom of trousers.
