I bought this 4 foot quilting set for $40, the open toe darning foot has been used, the walking foot (with guide bar) gently used, and the open toe foot and stitch in the ditch foot have not been used at all.
They are for Kenmore machines with horizontal bobbins. This foot set revolutionized my sewing, as it started me really quilting, but they do not work for my current machine.
I'm hoping to get $25 including shipping in the US. Interested?
