Learn to Snowboard

I have my 360s on lock now and i want to learn how to cork them. could somebody give me some advice or give me a link to an instructional video for them?
I spin frontside by the way

You can’t. It doesn’t work. You can only cork 5’s or more.

As far as help goes it depends on whether you spin frontside or backside.

If you spin backside try dropping your front shoulder and point it in between your legs.

For frontside you want to do the opposite and bring your front shoulder up.

It will feel weird but keep yourself locked in and smooth and wait till you touch snow.
