Embroiderer's Helper. This is the easiest, fastest way to make sure your shirt sew-outs are placed in the same position the first time, every time. Just line up the template on the shirt placket, mark the shirt, then hoop and sew with confidence. With the instructions printed on the template, it really is that simple! Embroiderer's Helper works on either the left or right side of shirts, sweatshirts and tees, and is made of durable polystyrene right here in the USA.
