I'm using two of these dog grooming arms to attach to my quilting machine table when I'm working on a large quilt. I can clamp the quilt up and reduce the drag on my quilting area. It allows me to quilt a large quilt in a relatively small space. The arms are easily removed from the clamp when I don't need them to support the quilt.  I got this idea from a quilter on the Sweet Sixteen facebook group and it works great. Product is sturdy and very versatile.
