I simply love your Scottish accents. I hope to one day visit Scotland. Thanks for the tutorial. I plan on going to the Texas Renaissance Festival this weekend and the theme is “Highland Fling”, so I’ll definitely try one wearing the sash one of the ways you demonstrated.
I always thought that , much like with a man's fly plaid, the brooch does not get pinned through the underlying garment. I, myself, use small safety pins to keep my plaid from shifting too much and remove the plaid when all the formal photos are done.
