There are many different stitching methods to sew on leather to lifeline and stanchion pole. We use two needles and cross the line in each stitch. You need to cross the needles in the same stich otherwise there is great risk you will sew in the thread and then you can pull the thread. It can look difficult but it’s really easy. To remove the lifeline you need to cut up the thread but you can reuse the leather again.
