If you are as I am, you may not want to poke holes in the Expensive Wool just for 'show'. I have two heavy thread loops on my kilt, that the pin goes into, when I wear one. If I catch the pin on 'something' I am likely to tear the threads outs, and not rip a hole in the apron. The 'rip the apron' factor keeps me from wearing a kilt pin for all but 'classy' reasons(wedding,R.Burns night ect)
