Urgent! Earflap Hat!

I’m in dire need of a pattern for an earflap hat. I have kind of skinny 100% alpaca yarn and 3.5mm circular needles. I need it for my brother so he can wear it under his ski hat, but none of the patterns that I have found online will work! Please help! I need one that has a simple intarnasia pattern on it!

Any help is appreciated!


Stranded rather than intarsia.

found one while looking at harry potter inspired hats for my son - look here

Plenty on my site (see signature).
