Pom Pom question

I’m trying to recreate this hat, and wondering what material to use to make the pom pom. It looks much finer than yarn, so I’m not sure if I should try to separate the strands of yarn after making a normal pom pom or if I should be looking for some other material to use… Any thoughts would be appreciated, thanks!

Welcome! It looks like the same yarn to me. Perhaps they made it and then brushed it or something? Or separated the plies?
