So, to celebrate, here's my pattern for a really easy rolll-brim hat. Not only is it easy, it's also fast (insert appropriate 'Your Momma' joke here), and only takes an evening to make (this particular hat took me a Sunday double bill of Columbo). It also has the magic power of fitting comfortably on different sized heads, from my own 21" scalp to Mikeyfox's Mekonesque 24" cranium.
You will be needing a 41cm/16" 8mm circular needle (the 8mm is the needle thickness, the 41cm/16" is the length of the circular needle). Don't be afraid of the circular needle, it's more scared of you than you are of it. You'll also need 4 dpns (double pointed needles). Yes, they are scary looking, and if you don't keep an eye on them they'll slip down the back of the sofa & perform acupuncture on you when you're watching old episodes of QI on Dave.
You'll need a ball of wool too, the chunkier the better. A single 100g ball should do the job (though you won't have anything left over. If you're worried, get more, it'll get used for something eventually). I used King Cole Homespun super chunky yarn in green, which is a nice thick wool/acrylic mix. You could use any chunky wool suitable for an 8mm needle, Sirdar Super Nova Tweed wool works really well too. (If you're really worried about the finished hat size, then knit yourself a gauge & work out the stitches per inch)
Cast 60 stitches onto your circular needles. Yes, it looks far too small right now, but it will work, I promise. Now comes the fun part, 'knitting in the round'. Yup, you're going to be going around in circles. Firstly straighten out all your stitches & make sure that they are all pointing inwards (or down, if that's your thing). You don't want to get your stitches twisted up, or you'll end up knitting a Mobius strip (a surface with only one side it may be, a hat it isn't). You'll need a stitch marker (Plenty of people buy stitch markers, they come in all sorts of shapes & colours. A paperclip works just as well. For this I'm using an Ankh ring sent to me by the lovely Cynthia as my stitch marker). Just slip it onto the needle next to the last cast on stitch. The stitch marker is just there to show you where the end of the row is. When you knit your row & get to it, you just slip it from one needle to the other & carry on knitting. It doesn't get knitted into the hat, just goes round & round the needles and helps you keep track of where your row starts/ends.
Hold the needle with the last cast on stitch in your right hand & the needle with the first cast on stitch in your left hand and knit into that first cast on stitch, pulling the yarn firmly to prevent getting a gap in the join between the two stitches (though this being a roll brim hat, no one will actually notice if the joint is a bit shoddy).
Sensible folk will recommend that you knit with the needles facing towards you, rather than away from you (like in regular knitting). I can't wrap my head around such things, so I knit with needles towards me, which has the bizarre effect of turning the hat inside out. But that's fine, just turn it right way round when you're finished. Work whatever method suits you best.
Another magic power of the circular needle is it turns a Garter stitch into a Stockinette. Why does it do this? Because you're knitting in a spiral, rather than the back & forth of regular needles. So if you want to make a garter stitch hat, you'll need to knit 1 round, purl 1 round & keep repeating. Or you can knit an inside-out, garter-that-becomes-stockinette magic-hat instead. Keep knitting until you have 6" or 7" or so of knitting (a little less if you're making a Beanie style hat, a little more if you want a big chunky brim).
Now comes the decreasing. Just relax. get yourself a cup of tea. Or a glass of wine. Who am I kidding, get a bottle of wine. Knit 8 stitches, then knit 2 stitches together. Repeat until the end of the row. Now knit 7 stitches, and knit 2 together, and repeat until the end of the row. Now knit 7 stitches, and knit 2 together, repeat to the end of the row. I'm sure you can see where this is going. At this point you & the circular needles will have to part ways. Yes, its time to meet the dpns, the double pointed needles -discovered by a the Mad Arab Abdul Alhazred in the ruins of Babylon & used to knit a cabled tote bag for his early draft of the Necronomicon. Wield them and despair!
You can just slip your stitches onto 3 of the dpns, spread them out equally & continue knitting the rounds of decreases. Or you can knit straight onto them, whatever works best for you. With the 4th needle knit off the dpns (it sounds complicated, but it isn't. Just take your empty needle in your right hand & the dpn with the stitches you need to decrease next in your left. Knit & decrease from left to right, and use the now empty left hand dpn to do the same again to the next one). Knit & decrease for as long as you can stand to (I keep going until I have 3 or 4 stitches, but I'm Peculiar), cut your yarn, leaving a tail of several inches, and thread through the remaining stitches. Tie off & weave in any loose yarn left (don't forget the bit at the brim where you cast on). Turn it right way around (if you've been knitting it inside out)
There you have it. A very fine hat.
You can play around with the pattern. If roll-brim isn't your thing, then a rib stitch for the first couple of inches works well, and gives it a bit of elasticity, too.
