Anchor Post Demonstration
This video shows the 1/4" thick anchor post that is used with rotating TopAnchor templates. The wafer is inserted underneath the anchor post to give stability to the template when quilting on a longarm machine.
TopAnchor Quilting's thinner free motion templates use a thinner 1/8" thick anchor post without the wafer. Free motion quilters already have the firm bed of their sewing machines to give a good solid base for their templates and don't need the wafer.
