Best increase for a hat

I’m going to knit this hat pattern:

In round 11, I’m suppose to do 9 increases. What’s best increase I can use? kfb? M1B? M1F?

For a minute I couldn’t figure out why you were increasing on a hat that was started at the bottom. Check the tabs at the top of the forum and look at the increases. See which one works best for you. KFB leaves a little bar so if that bothers you you may want another one.

Thank you :happydance:
