I like using old sheets cut in to 10 inch squares, from there I lay down a strip and then another on on top of it right sides together, then I flip that one over and iron. I repeat process until block is covered then I stitch around the edge of block so nothing comes undone while I'm making the other blocks. I only do these when I need mindless sewing, therefore I also pin them in 10 block stacks so I know when I have enough for a quilt. When the block is done if I want embroidery on it I do that before I pin them into 10 block stacks. I'll use this method also if I'm doing the QAYG process. Clear as mud right, LOL I press as I do...........
