Quilting adventures: Mass Production Half Square Triangles..... a tutorial....! I've been using Thangles, but this tube method looks like it might be a lot easier--will need to get one of these rulers.
Templates from TopAnchor Quilting Tools come complete with the anchor post and stabilizer pin, which are attached to the quilt top in the working area. The templates fit over and rotate around it. Can be moved as desired to create patterns in different areas of the quilt with your longarm quilting machine.
