[Eeyore]

So I have come to the conclusion that its time that I pick up all my airsoft and paintball guns off the floor in my room and den and hang them on peg board. I bought said peg board a few days ago and now I have no idea how to properly hang it. I need some help guys. If I just screw it into the walls at the corners it will be flush with the wall and hen how would the pegs/hooks etc be secure. Any help would be most appreciated. I've seen photo in the show us your armoury post oof gus on peg board, so I know some of you know how to hang it. Thanks
