I found this wonderful stitch in Helan Pearce's book entitled, Beaded Dimensional Embroidery. It is put out my Milnar Craft Series and I think it is my fvourite book this week at least!
I am using it in a motif but I think it could lend itself well to a seam treatment as well. There is a tutorial for this stitch in the next post which I hope will explain how it is done adequately. If you have any questions or something is not clear please just ask. Thank you!
