I was researching "once again" the circular stitching foot for my Singer L-500 and FW75 to see what it looks like and looks like I may already have it in one of these Singer machines accessories. I'm pretty sure I do just have to find it.
Anyway I found this site that teaches you how to use your machines foot attachments and figured some of you may want to check it out. You will find it by clicking http://jennys-sewing-studio.atbinter...nstruction.asp
I'm sure it is a good resource no matter what type brand machin you have.
