NARROW SASHING: 1. Quilt blocks = top + batting + backing, quilt all the way to edges. 2. Sashing: sew top & bottom strips to 1st block with SAME seam. 3. Join: sew bottom strip to next block, open blocks out and lay flat. Edges of blocks should meet. 4. Finish: slip-stitch top strip to 2nd block by hand.
