The BERNINA Large Freearm Embroidery Hoop (5.7" x 10" max. embroidery area) enables the use of the BERNINA freearm with tubular items, such as pre-made bags, or T-Shirts, without requiring unsewing and re-sewing. Thanks to this unique technology, you will save on additional stabilizer and fabric for hooping while enjoying the benefits of freearm embroidery with larger projects. Moreover, the ergonomic twist-lock mechanism lets you hoop your projects with even more ease. Close the hoop by turning the twist-lock until you hear a distinct click.
