Are should have been "I". 😊 That was a typographical error. Embroidery machines require that you place stabilizer in a 2 piece hoop with the fabric that you plan to embroider on just as you would do with a manual wooden hoop. A newer hoop is magnetic which includes a one piece metal frame with magnets instead of a two-part hoop that you tighten and then attach to the machine. The magnetic hoop allows you to "float" fabric on top of the stabilizer and frame as opposed to inserting it between two parts, which works better for thicker fabric or towels. Adhesive spray lets me temporarily "stick" the towel or fabric to the stabilizer in the hoop so that it doesn't move while being sewn.
