The Merrow MG-3DWRL sews a tight and narrow rolled hem on delicate fabrics such as silk, nylon tricot, and similar sheer material. Like all Merrow MG Class sewing machines, the MG-3DWRL is engineered to sew consistently and uniformly, and will last for decades with routine maintenance.

The MG-3DWRL sews at high speed (5500 RPM), but will not pucker or curl fabric during operation, resulting in a tight straight-hanging seam. It is engineered to handle delicate material and sews sheer and gossamer materials exceptionally well.

The MG-3DWRL utilizes a specially adapted needle plate and presser foot finger which fold the material down before sewing, and sews a long and straight yet dainty seam.

Because of its fabric handling capabilities, the MG-3DWRL is used to sew delicate garments such as women's lingerie and sleepwear. It is also used as an edging machine for sheer curtains and other applications that use lightweight synthetic fabric.
