Quilting On The Grid is a new patented quilting technique that makes it possible to make a beautiful reversible quilt using a straight-stitch sewing machine and Mary's Sew Genius (TM) foundation. The foundation is stabilized and pre-quilted in 1" grids enabling you to attach fabric strips or piecework strips directly to both sides, sewing them on at the same time . We offer Mary's Sew Genius foundation in rolls 45" by 15 yards and in pre-cut packages. Our website has downloadable free designs/patterns and instructions. Instructional videos are available on our website, YouTube and Facebook. "Sew a straight line-make a reversible quilt!"
