Here is an Original Darning and Embroidery foot

ORIGINAL SIMANCO PART 121094

It is for use with the Featherweight 221k and 222k and will also fit many other models as long as they are Low shank sewing machines

The spring on this foot allows it to move up and down as you're darning or embroidering so that the fabric does not rise with the needle as it goes up

This has no broken or loose parts and in excellent condition
