So you will never have to search for a basic hat pattern again: (for circular or double-pointed needles): 1) knit a swatch and measure your gauge
2) measure your head (or if it's not for you, measure the head of the person it is for. Or, one of the links just posted had a chart of standard hat sizes).
3) Multiply your gauge (stitches per inch) by the head circumference.
4) Subtract about 10% from that number (for a snug fit). You may want to adjust this number a little so it is easily divisible (see step 6).
5) Cast on that number of stitches, join to work in the round, and knit for 8 inches (9 for peole with larger heads, or if you intend the brim to fold up). If you work in plain stockinette stitch (all knit stitches), the brim will curl. You can experiment with ribbing (k1,p1, k2,p2, etc) for a different look. I usually use a set of needles 2 sizes down from the ones I swatched with for the first two inches or so, or for the desired lenght of the ribbed portion.
6) Pick a number that divides easily into the number of stitches you cast on (for example, if you had 60 stitches on your needles, you might use 6): we will call this number x. Subtract one from this number: x-1.
7) Knit x-1 stitches, then k2tog. repeat across the round. (if we were using my example from the last step, you would k5, k2tog) Knit the next round plain. On the next round, decrease after every x-2 stitches
8)Continue this way, decreasing on every other round, and having one less stitch between decreases each time. On the last round, K2tog all the way around (if you are using circs, you will probably have to switch to DPNS when you get down to the last few decrease rounds). Break yarn and thread it through the remaining stitches, then pull on it to close the top. Weave in ends.
It looks like some of the strands are knitted (i-cord), or crochet chains. It also looks like some are just a buch of strands of yarn twisted together. I think you could get pretty much the same look without knitting or crocheting, though. I think it will take a lot of yarn and ribbon scraps, though. I hope it comes out well.
So, I have about 350 yards of mohair yarn (I think it's fingering weight) in a lovely dark brown color. Any ideas about what I could do with it (other than an shawl)? So far the only thing I've thought of is a mobius scarf or stole. Thanks!
