Longarm quilting is the process by which a longarm sewing machine is used to sew together a quilt top, quilt batting and quilt backing into a finished quilt. The longarm sewing machine frame typically ranges from 10 to 14 feet in length (or, 3metres to 4.25 metres). A complete longarming system typically consists of an industrial length sewing machine head (19 - 30 inches,) a 10 to 14-foot frame, a table with a layer of plastic under which is placed a pantograph, and several rollers on which the fabric layers and batting are attached. Quilting using a longarm machine can take significantly less time than hand quilting or more traditional machine quilting. This time saving is a large factor in the gain in popularity of longarm quilting.〔Knight, Lois. ''Longarm Quilting? What Is That?.''

The first quilting frame and machine consisted only of two bars that allowed the user to move the quilt and the frame beneath the machine to quilt straight, parallel lines on the fabric. By roughly 1877, the design had been modified, and began to look similar to the design quilters now know as a longarm quilting machine. Before electricity, the operator used a hand crank to move the machine along the rails and over the fabric.〔''Machine Quilting in the 19th Century.'' Harts Cottage Quilts. 2006 . Harts Cottage Quilts. 18 Mar 2008 ()〕 Almost 30 years later, the designs and patents for quilting machines had changed drastically.〔 While the Depression era caused a decrease in the interest in sewing machines and an increase in hand sewing, the quilting machine still managed to take on new and exciting designs. During the past 20 years the longarm sewing machine has become a popular and familiar concept to quilters.〔(''The Cozy Quilt Patch.''
