Help! How Can I Add A Face Bandana To A HL2 Model??

Hi! I’m Making A Gmod Series, And I Want To Make A Character That will be like “Me” In The Series, Like Elliot’s Character From Elliot Goes To School.

But I Didn’t Found Any Idea, Then, I Tought That That Would Be Cool If I’ll Just Take An Rebels Character, And Add it A Face Bandana, So that Would be My Player Character.

I Heared Many Ways To Do It, But I Would Like To Know With Way Is The best!


(BTW, I Will Give Credit!!)
