Check out Bayside Quilting, fun and done section. They have many quilt patterns using their method. The one I made turned out great,and there were no sashing strips. I made the block quilt samdwiches this way, the batting and the top were the same size the backing bigger. After you make the quilt block, you sew them together and then topstich the seam down. Their is a video that will make it very understandable.
