How to knit abutton?

Hi folks!
My first time logging on. I just finised my first sweater, I think it would look great with a few knitted buttons, so how do I make knitted buttons? Thanks,
Lini

You don’t say what style you’re looking to make. Round? Flat? Or?

Round concept here:

Crocheted buttons, using plastic ring, are easy and flat.
