The EZ Cap Frame seamlessly attaches to any Durkee Blue Adaptor Arm designed for Multi Needle machines. With its large 5" x 4" stitching area, you can easily embroider either the front or back of a cap. Since the stitching is done flat, no specialized digitizing is needed. Additionally, you can use extra EZ Frames to embroider the side(s) of a cap. (Note: A Durkee Blue Adaptor Arm must be purchased separately to utilize the EZ Cap Frame.)
