Having started the Noro Daria belt months ago, I have now finished it. The Daria was beautiful but tough to knit with, as I was keeping the tension tight, not wanting too loose a stitch (should have used smaller needles, probably). Due to its composition this yarn (if you can call it that) is quite stiff and springy. For instance, once it's been wound into a ball the ball will readily unwind itself unless you keep it in a bowl of some kind in order to restrain it. But it's pretty - it has a luminous lustre about it. I like it.
The finished belt is quite stretchy but firm - it's just perfect to wear with anything, really (anything in the right colour, anyway). I massacred an old denim belt for the buckle and it's just perfect, which is handy as I couldn't find the right sort of buckle online (not under about £15, at least).
The stitch is linen stitch, on 5mm needles with nineteen stitches cast-on. At the tapered end I just changed to garter stitch and started knitting the three middle stitches together every row and that gave it its tapered shape. I used exactly two skeins of Daria. I'll definitely be wearing this belt.
By the way, thanks to you all for the kind comments on my cape. It's really fantastic to recieve feedback on completed items, isn't it? I appreciate it.
