Why? I dunno, I think people will watch them. I made a sweater, and did some things that are hard to explain in words. My basic design is good for alpaca because it does not depend on a highly crimped fiber. It is perfectly fine just hanging and I can even tuck it into my pants if I want to.
I don't have photos yet and it's not really fancy anyway but looks good on me. I gave it a split welt hem that is rounded. It was knit top down with a somewhat unique cast on. It's also seamless. In all it's good for meeting/TV knitting.
The above is an attempt to explain the magic cast on that I posted last summer.
