Take some hair on the side, twist it and tuck it behind the headband (in from the top).
No problems if it sits loosely
Take some hair from the back of your hair and also tuck it behind the headband (in from the top).
Do this to the other side
Now just push all of it in
Get it balanced and then fix it with a few hairpins.
