Here's a common foot just to get it out of the way. ;)
Singer Rolled Hem Stitch Attachment
"SIMANCO 120855"
This one is in nearly everyone's attachment box.
I've used it to hem a table skirt for the cutting table in my sewing room.
This is demonstrated on my 221.:thumbup:
It takes a little practice, but using "Londa's Technique" as I found on you tube, it's not as difficult as you may think!
