I was pinning while making the blocks for the farmers wife quilt blocks but found when putting so many small pieces together can creating so many seams, pinning moves the fabric a smidge and that was throwing some of my seams or points off enough to make me quite frustrated. I had the bright idea to use my small red clips that are used for holding binding and had much better results with matching my points. The fabric doesn't move when you use the clips, you can put the tips of the clips right where your seam will be so you can fold your pieces open to make sure they are right were you want them and the clips are flat on the bottom so you can sew right up to the edge of the clip before you have to remove them. I love them and no longer pin when I am piecing.
