This is a version of Palestrina Stitch which is simply worked on many types of fabric forming a highly textured attractive knotted line. It can be used for outlines and linear elements.
It can also be worked as an isolated stitch. A firm twisted thread, such as pearl cotton, show the knots to their best advantage.
Work the stitch from left to right, along a line. Work a Palestrina stitch three times over the bar instead of moving along the line after the first loop.
(see the illustrations)
Space the knots evenly and close together to produce a textured line which follows a curve.
The knots can be worked closely together to produce a heavy line or spaced quite far apart.
Sorbello Stitch is also an interesting variation of this stitch.
