I recently purchased a beautiful vintage WWII cap badge of the Seaforth Highlanders that I want to attach to my balmoral hat. Below are pictures of both the badge and the balmoral. I would like to attach the badge the correct way so I ask for your assistance.

I assume the posts on the back of the badge are folded down inside the hat to secure the badge cap. If that is not correct, please tell me.

A couple of novice questions:
1). How do I go about determining the measurement of where the holes in the hat should be?
2). What is the best means to poke holes into the cap?
3). How do I align the badge to the left side of the balmoral?
4). How far off the hat ribbon should the badge be positioned?

Any advice (and pictures) is greatly appreciated.
