I posted this on another thread. My biggest problem was figuaring out how to get the fabric edge straight so pattern repeat can be cut. As far as the inner sashing I sewed cut border strips on each SIDE of the square and then sewed a peice cut the block measurement made of the outer sashing with a strip of the inner sashing on top and bottom to join squares together in strip. Then I followed pattern instructions on sewing cutting, and adding outer sashing with corner stones. I found it time consuming but I took my time to make sure I kept in the right order. There may be an easier way that an more experienced quilter can share with us. ( I only started quilting about 1 year ago)
