More wristies....these use a technique that I've just learnt (thanks Catherine) of casting on then casting off, which gives the little, or long, dangly thing a cute little twist.
It is all in the twist, as I keep telling people at the moment. Twist holds fibres together, makes them soft or strong and gives them purpose.
One interesting aspect of twist is whether, as you knit, you twist or untwist the yarn. This can be important. For instance, you probably want more twist in the cast-on, cast-off edge, as it will be stronger.
My investigations, so far, have also shown that twisting at the edges makes them neater. I don't know how much this depends on your knitting style. I knit continental, but even that I think I knit oddly. One thing I do know is that if I do a knit stitch, I twist a 'S' plyed yarn.
See, it's all in the twist.
