I haven't made a quilt using either of the two methods you mentioned, but want to try the one that you bring the back forward to make a sashing strip. However I have made three quilts using Sharon Pederson's Reversible quilts which is bqasically the same method. With Sharon's method you cut strips and join the blocks to make the sashing, and with her method you do a lot of hand sewing. You might want to try her version of making quilt as you go. I don't know how much you enjoy hand sewing. I am not a great fan myself, but the three that I made using her method were large quilts, two king size and one queen. If you check out the pics. sections on this board and view "Hope's Rose Garden" by Gerbie is one of the quilts I made using her method, and it was a king size quilt.
