This 6"x6" Square Embroidery Frame is an ideal size for embroidering on clothing, quilt squares, and for embroidering the decorative lettering built-into select machines. The large lettering built into these models will fit perfectly within this hoop, when embroidered singly, without the built-in decorative frames. The smaller decorative lettering built into these models fits perfectly within this hoop, with room to include the built-in decorative frames around your lettering! Free software upgrade available for Quattro 6000D and Quattro 2 6700D.
