I guess my questions are.....it draws the 1/4"sewing line......why,if one has a 1/4" foot on sewing machine that should be the guide....and what is the drawing ink....is it permanent or washable ....one piece of fab at a time seems like it is not a speedy process for piecing....so I guess it will be something an appliqué techniquer might welcome, but that too might be more time consuming......will wait and see. It will be interesting how the LQS will be pushing this product......
