4.375" Round Mighty Hoop
This hoop has an inside dimension that is 4.375" round (111mm).
The actual sewing area will be less, depending on your machine's presser foot: approximately 3.6" or 91mm.
This Mighty Hoop was designed for items like sleeves and cap backs. Unlike the original Mighty Hoops, it was not made to hold thick and heavy items. It was designed with smaller magnets allowing it to have a smaller outer ring. This makes it easier to get into tight areas. It will not be able to hoop thick bags, workwear, leather, or other difficult fabric. The 4.25"square Mighty Hoop would be a better option for that type of embroidery.
This hoop can be used on a Brother VR 1 needle, PR 6 needle and PR 10 needle machine.
