A fabrick choice note here, if you do this, stay with the wool tape trims, or perhaps linnen
I've recently found out that mixing wool and linen in the same garment is not kosher, thereby making a kilt unwearable by a person of the Jewish faith.

Wool kilt, wool tape = ok
Linen kilt, linen tape = ok
wool kilt, linen tape (or vise versa) = no way
