The Singer sewing machine zigzagger 4 pack includes four red stitch pattern cams (model 161008). Are for the Singer 221 or 301 sewing machines. I believe these are the same 4 that comes with the zigzagger. These cams enable precise stitching variations, enhancing creativity and versatility in sewing projects. While the booklet is missing, the product’s compatibility with Singer sewing machines ensures integration without complications, allowing for a seamless sewing experience.
