Photo shows 3/8″ but listing is for 3/4″ 100% white cotton twill tape, same manufacturer same packaging just wider. We recommend wrapping the inner ring of an embroidery hoop, no matter the type of ground fabric. When wrapping, make the overlapping wraps at a 45 degree angle and do it firmly. Tack with a few cross stitches to the inside of the hoop. Wrap the outer ring if you are embroidering on fine silk fabric or anything that will mark.
