I made for myself about 7 or 8 strips of white fabric about 3/4 to 1 inch wide and 2 inches long. Then I used a Sharpie and marked on them (for instance) R1 B1 for the first row, and so on. I pin them on the top block when the blocks for that row are all stacked, beginning on the left side of quilt. When finished with them I just pin them in order. Oh, I also draw a little arrow on them, pointing right if I want all those block seams pressed to the right, and next row, the arrow points left. I just keep these to use over and over.
