I am just about to begin a project where I cut two rectangles 6.5 x 21 inches and then place a piece of paper and follow the lines with the sewing machine. When I am done, I cut the paper, peel off the pieces and press open 27 HSTs. They are produced by Laundry Basket Quilts and make many more HSTs at a time than Thangles. Anyone have experience with this method? Advantages? Disadvantages? Hints?
