Men's beanie pattern?

[Happychik]

I was going to knit both my BIL's a beanie for christmas, almost finished the first one and ran out of wool (was a discontinued line) so it became a beanie for Quinn. Anyway I think there is no way I'm going to get two more knitted before christmas along with everything else I have to knit so was thinking I could sew them a merino beanie each as I have heaps of merino - does anyone have a good pattern link?
