Tell newbie about kilt pins

[Pleater]

If you wear a pin do be sure to wear it high enough so as to avoid your knee in all circumstances.
My mum used to put a simple pin in my kilt through both layers and low down, and horizontally. It hurt when it got in the way, but one day I dropped to my knees and the pin was opened up and pushed into my knee behind the kneecap - I can still remember it vividly, both it going in and the teacher pulling it out.
