This week's stitch is the Sorbello stitch, an old stitch that originated in the village of Sorbello in Italy. It is closely related to the Palestrina Stitch that we used in Week 28. According to my research, Sorbello Stitch is a common stitch used in cross stitch, needlepoint and embroidery. I have to admit that it is a new one on me!
There is a set of diagrams in Sharon B's Dictionary of Stitches which should be very helpful. You can also read more about the use of this stitch in Embroidery Stitches by Mary Webb at Google Books - the photograph of the stitch in progress is especially good there.
When you try this stitch keep in mind that it needs to be worked fairly loosely. A looser tension really allows the beauty of this stitch to shine through. It is a lovely stitch to do - simple yet effective - and a great rhythm develops as you are doing it. I hope you will give it a ry. Enjoy and have fun!
