About this machine

The Brother Project Runway Limited Edition LB6770PRW is a sewing and embroidery combination machine with 67 built-in sewing stitches, 98 stitch functions, ten one-step buttonhole styles, 70 built-in embroidery designs, five monogramming fonts and a 4 x 4 inch maximum embroidery field.

This was Brother's first Project Runway model with embroidery

Brother describes LB6770PRW as the first Project Runway machine in the line to offer embroidery. That is useful model history because the Project Runway label appears on several sewing-only machines as well.

The sewing and embroidery counts describe two sides of one machine

Brother lists 67 sewing stitches and 98 stitch functions alongside 70 embroidery designs, five monogramming fonts and 120 frame pattern combinations.

The field remains 4 x 4

Brother Support lists LB6770PRW among the machines with a 3.93 x 3.93 inch maximum embroidery area. A larger multi-position hoop can hold more fabric, but it does not increase the size of one design.
