Pattern for felted beanie hat

Does anyone know of a pattern for this? There are lots of patterns for touques but I would like to make one that I can felt. Is there a formula for adjusting patterns so they can be felted? TIA

i recently did a felted bucket hat, of course i can’t locate it now but found it online, anyway after i felted it it looked heaps like a beanie, i had to really tug it around to get a brim, it was on a site called knitting on the net, if I knew how to I’d put a link but sorry!!

I did find the link, thanks, a great site
