The predecessor of the 18E Crochet Machine was first patented in 1877, and since then Merrow has been refining and perfecting the machine's engineering and performance. The 18E produces a beautifully flat and uniform finish on heavy materials such as wool and fleece, and the 18E stitch is the standard when it comes to decorative blanket edging.

Primarily used for blankets, the Merrow 18E can be used to finish a variety of articles with a decorative crochet edge. It is built on Merrow's cam-driven architecture and uses the latch hook system pioneered by Merrow's founding father, J.B. Merrow. The 18E is a timeless piece of machinery that continues to set the standard into the 21st century.

The MG-3D is a version of one of Merrow's MG Class Hemming Machines that has been modified for use on woven blankets. The MG-3D sews a standard 1/4" seam which can be modified according to application requirements, and it sews a unique stitch that is slightly smaller and tighter in appearance from the traditional Merrow Crochet.

The MG-3D decorative edge is a functional stitch that covers jagged ends and hides loose fibers, and any of its three threads can be varied in color to add further accent. At 1/4" in width, the MG-3D stitch is frequently applied to smaller blankets such as throws and afghans which can be overwhelmed by larger crochet stitches.
