MARTELLI 12" DESIGNER HOOP RULER LARGE SHORE WAVE
MARTELLI SW 016-L 12" DESIGNER HOOP RULER LARGE SHORE WAVE
Our designer hoop rulers are made of clear acrylic so you have an unobstructed view of the sewing head. They snap easily into place in the hoop, and remain secure during use. We recommended using these rulers with a rolling presser foot; also works well with most open-toe and saucer presser feet.
