If it is the one I am thinking of -- You use a border print or stripe. You cut two strips, with the bottom part being what you want as the perimeter of the table runner. Then cut a 60* triangle from both ends - being sure that the point is toward the bottom of the strip. You then need 4 more triangles cut with the wide bottom on what you have chosen as the perimeter. Lay out the runner with the SHORT sides touching. Now put 2 triangles into the space on either end. Hope this is clearer than mud.
