This pattern was presented by one member of our class so I don't have a source for you.
1) Cut iron-on batting the desired length of runner. Position the center square of focus fabric on point.
2) Turn over, center the first strip of the opposite fabric from point to point. Sew additional strips alternating on either side until center square is quilted in place. trim to match size and shape of front square 3) seam 4 small triangles of 2nd focus to edges of trimmed strips. Press in place. 4) Turn over to 1st side, seam strips outward from center, automatically quilting triangles on 2nd side. 5) Con't alternating medium and small triangles and strips until desired length. Hint: Draw perpendicular and diagonal lines on batting to keep the runner square.
