Many people piece their quilts together on the sewing machine; regular sewing machines are excellent for this. Some standard sewing machines can also handle the actual quilting process—sewing the top, batting, and bottom of the quilt together with a plain or decorative stitching pattern. However, a large comforter is difficult to quilt by machine because of the lack of room on the machine bed. Feeding a very thick batting through a standard sewing machine can also be difficult.
If you do a lot of quilting, you may want to consider a long arm quilting machine. A long arm quilting machine quilts a quilt set in a frame. Long arm quilting machines can stitch the quilt in a variety of stitch patterns and allow you to quilt an entire quilt much quicker than by hand or even by using a standard sewing machine.
These machines are not for everyone. They are rather expensive and they require a lot of room; ideally, you need a separate room to accommodate the machine and the frame; however, if you quilt many quilts each year, you may enjoy a long arm quilting machine. Long arm quilting machines are relatively easy to learn to use and many quality machines are available from a variety of manufacturers.
