Cowboy hat?

Hi. I’m new to knitting and this forum. And I have a couple o’ questions if any one can help. Ok grandma bought my 8mo old a cute suede jacket. It looks really cowboyish. So I thought why not knit him a cowboy hat. But how do I get started? How would I make a rim? Any suggestions would be greatly appreciated. A pattern would be even better. :wall:

I don’t have a clue about how to make something like that w/o a pattern.

This member made one, but it’s adult size I think. You might ask her about the pattern.
