User:Blackboomerang/Saddle Stitch

Saddle Stitch is a sewing technique. Commonly used on saddles[], it is used is areas where both sides of the work will be visible, such as around the outside seam of the saddle where the seat is joined to the tree or support structure. At it's simplest it is performed by having a needle on both ends of the 'thread' and passing them both through the same hole, but in opposite directions. Thus it looks like a nice neat stitch from both sides, although it is not quite as simple as it sounds. The appearance, although nice, is not the primary reason for using the stitch. To be done properly the needles are pushed through in a sequence to ensure that the thread (usually a heavily waxed light twine in the case of a saddle) overlap in the correct manner to lock the thread in place, effectively knotting each stitch, locking it in place. Done properly, the stitch can hold for a short time even if the exposed thread is worn away.
