I am almost to the end of the first ball of yarn and for all intents and purposes, the hat is long enough for a child's hat.
I suppose I really ought to go read the pattern. Yeah there is always that isn't there. Read the pattern.
I am using a different pattern than for my wee prince's hat but that was only done because I was using a very different weight yarn. The two hats finish off the tops very differently. One uses a graduated series of decreases and the other grows wider and then finished up with a set of dramatic quick decreases. I haven't decided which of these two topping off methods I will use.
Or maybe none. Maybe I will do my own thing. That will be tomorrow's thing to think about.
