Don't forget to put a piece of wide rubber band on the pin in back so you don't lose the pin. They do sometimes come unhooked and slip away without notice. Running the pin through a piece of rubber band on the backside prevents that. You'll notice a thunking against your leg if the pin comes undone - but it will still be there.

And, follow Ham's advice - one kilt pin per kilt and leave it in - that way there's less damage to the cloth. Also gives us the joy of kilt pin collecting/addiction.

Sort of humerous/sad to see posts about finding a kilt pin heavy enough to hold the apron down in a wind, or sewing weights into the bottom of the kilt.

All one needs is an underkilt/slip-like garment under the kilt and practice walking in the wind in various directions until you get used to, and comfortable with, the wind dancing in the kilt pleats.

Well, and learn to avoid updrafts if possible...
