SINGER 161825 Vintage Cover Plate for Free Motion Work Embroidery Buttonholing
I was somewhat disappointed to see that it is stamped. I was expecting it to be machined like the throat plates. No matter it is of good quality, fits as it should and provides an excellent work surface. I was pleasantly surprised to learn that it could also be used with my buttonholer. All in all I am very pleased with it and recommend it to anyone...(if you can find one). If you see one, grab it.
have been using this button hole attachment for many years very successfully. with 20 cams, it makes up to 1.5" button holes in various styles with complete control to use on many types of fabrics....
