Billed slouch beret for chemo patient

My 12yr old granddaughter is undergoing radiotherapy & then chemo and wants me to knit her a billed,slouchy hat which I cannot find a pettern for, has anyone got one they can share. I have some kniotting cotton which knits up as 8ply that I would like to use, thanks.

See if one of these would work. You can make it slouching by increasing after the edge.

The term 8 ply isn’t really useful… What weight our gauge is the yarn? You may have to alter the pattern to work with your yarn.
