Add sashing and cornerstones to the bottom of the first row, before adding the second row. Next the 4 blocks are sewn together in a row.

The second row and all remaining rows has the sashing and corner stones added to the bottom of the block and the sides and those blocks sewn together in a row. When all the rows are made, then just sew the rows together. I always put my quilt on graft paper and hang that on my design wall to keep checking it as I sew, but it really is very easy and fast and accurate as well. Hope you try it for yourself.
