I've got a low shank left homing straight stitch foot...& a narrow hem foot. I got them in a box of attachments I bought at Goodwill. The straight stitch foot is easy to spot...The narrow toe is on the left rather than the right. The straight stitch foot is nice to have if you want to use the left needle position (on a machine that has L, C,& R) & need the control of a straight stitch foot for sheers, silkies, etc....even if your machine doesn't home to the left.
