I need help with my bitcoin, Please Help!

Hi peeps, I really would like to store my bitcoin offline on a USB stick, however I find it a bit of a mine field and would really appreciate some help in learning what the best practice for this is. If someone can help me It would be very much appreciated.

1. Do I need to set up a wallet then put that wallet on the USB and then transfer that bitcoin to that wallet?

As you can see I am clueless!

Please Help!

Many thanks
