We just had a fun sewing day at our quilt guild making string quilts. We used telephone book pages cut 7 X 7 inches. Start with a 1 3/4 inch strip of black or white in the middle, then sew and flip any or all colors with a smaller stitch. The squaring up is very easy, because the paper is your cutting line. Remove the paper from each square after you square it up. Also ironing is important, or you might have a very wonky square! The paper comes off very easily, only a few seconds for each square. When you put 4 blocks together to make one bigger square the blacks or whites then form beautiful diamonds. google images of string quilts..there are so many beautiful ones!
