The BERNINA "Hoop 'N' Buddyz" embroidery hoop insert makes it easy to embroider caps as well as fabrics that are slippery or difficult to embroider. This hoop also ensures a tidy and accurate result on uneven fabrics. Sticking the material to the adhesive fleece clamped in the "Hoop 'N' Buddyz" embroidery hoop insert creates a non-slip surface for easy embroidery of motifs, patterns and lettering. This embroidery hoop is intended for use with the large, oval embroidery hoop.
