Janome Concealed Zipper Ft Horz
"High-quality ready-to-wear garments frequently feature invisible zippers, a detail often overlooked by home dressmakers. However, using a Concealed Zipper foot ensures consistent success. Invisible zippers work seamlessly with various fabrics, from delicate silk jersey to heavier wools and tweeds. This specialized foot positions the needle close to the zipper teeth, seamlessly integrating it into the seam for a polished finish."
