High Quality Content by WIKIPEDIA articles! The Sailmaker's Whipping is one of the most durable and stable of rope whippings known. It is second only to the nearly indefatigable palm and needle whipping.The twine is first threaded diagonally through the rope. The twine is then wrapped round the rope including the diagonally threaded end. A needle is then used to thread the two ends through the rope to enclose the wrapping turns. Finally a reef (square) or a string of reef (square) knots is tied. Then this string of reef (square) knots is pulled through the rope to bury the ends.
