This is exactly what the antique singer embroidery foot does. It costs like 800$ plus if you can even find it. It is so pretty. I hadn't though about guiding the heavy thread by hand. It would work with yarn and crewel and other fibers too. Super awesome!
I LOVE THE APPLIQUICK TOOLS❣ I am an artist that also quilts; these ARE A MUST HAVE for me and the scissors too. I can't wait to get them. Thank you, Rosa 🥰
