I just completed a string quilt - I draw two diagonal lines about 2 1/2" apart on each square - Then stitch and flip fabric on each side of the line. When the blocks are put together it looks like there is a white path around each block. This is such a simple and fast quilt to do. The pieces in mine were chosen because they were odd cuts or less than a fat quarter. It didn't matter if they were brights, civil war, pastel or dark - it turned out nice.
