Beautiiiiiiiiiful block Mirabelle. No, that's not the 'furrow' I am worrying myself about...this quilt is designed from the outside in...borders then next steps in for six steps. For a triangle, she cuts two 2 3/4 inch squares, sews once across the middle, and trims the under side of excess. Have done the center first, despite the instructions and finishing the last of four Iowa star designs. Its her 'scant' quarter inch seams to get the measurements to come out right...I had to add 1/4 seam allowance to get the Iowa star design to measure as a nine inch finish block. Will try emailing some of the measurement problems. Thanks for the offer.
dublb, great job on your quilt.
