Hello Quilting Friends. I am hope someone here can assist me. I am trying to find some info on the Singer Style-O-Matic attachment. It came with a box of misc attachments I got at the thrift store. What I have found says it is an 17 in 1 attachment. It comes apart and can do all kinds of things. Can someone tell me it's worth as they seem to be very rare. Is it something I will use often? I love this site and the info gained on here is unbelievable.
