I'm guessing you're speaking of matching seams when sewing 2 blocks together? I would pin for hand piecing the same way I pin for machine piecing...I put a pin straight down top to bottom through the seam on the top piece, then take the bottom piece and place that pin through that seam. With that pin still vertical, I place a pin as closely as possible on both sides horizontally through both pieces of fabric and then remove the vertical pin. I do this at each intersection. I also pin with the head of the pin on the outside edge of the fabric. You could then hand sew with the edge of the fabric towards you to reduce pin sticks. Hope this helps.
