Is the button closure at the top of the head at widest part?
First measure your head, that is the measurement you want it to fit. Make it a little smaller than that measurement(an inch +), so it has some snugness to fit.
Cast on however many stitches wide you would like it, say 2-4 inches. Continue knitting in a garter stitch(or any stitch you like) till evenly in the middle of the headband( 1/2 of head measurement). Then at this middle place, decrease for 3 or 4 inches so headband is narrower in the back . Increase again evenly to finish the headband .Adding a buttonhole in the 4th row from the end . Bind off. Add a neat vintage button.
