Here is another finished object. I did it earlier this fall, but was waiting for the designer to release the pattern before sharing it with you. It is called "Burning Love Hat'' and can be found here.
It is really a great cabling pattern. And she even gives hints about how to cable with-out a cable needle. Which, by the way, I totally get the hype now- it is a very handy technique especially when working small cables (one or two stitches).
There are four sizes ranging from toddler to adult and it is super fast (a couple of afternoons), pretty darn easy (despite all the cables) and heirloom quality once finished (if I may say so myself). All you need is a size US8 16 inch circular needle and a skein of worsted weight yarn (I prefer wool). Like cake.
The only thing I can add is to check it along side your favorite beanie to make sure the length is alright before you start decreasing. I wish mine was just one repeat longer...
