When quilting on domestic, longarm, or with embroidery this marking tool i essential. Reference lines give a much better result.
The Westalee Design 8 Point Cross Hair Ruler is for marking 4 (90o), 8 (45o), 16 (22.5o) or 32 (11.25o) reference lines.
When using rotating templates, reference lines will give much more accurate spacing. On a domestic machine the quilt is not as taught as on a longarm machine and there is movement of the quilt sandwich which can make it difficult to use the rotating lines on the templates. We like using our Cross Hair Ruler to locate the center and mark 4, 8, 16 or 32 lines, as required.
