Last stitch sunday, we have seen fly stitch with beads. Fly stitch is fun with or without beads, but the question about stitches is, what to do with them? Fly stitches can be worked one below the other to form a plant like structure. i actually prefer this kind of thing over fern stitch for most applications, because the fly stitches look somewhat more organic.
As an additional tip, to give a more pronounced look to the twig, you can whip or lace the middle line made by the fly stitch tack down stitches like you would do with back stitches. I have no pictures for that right now, sorry.
