I love the Saltire but I don't like it on a kilt, especially upon the seat.

I love the Draig Goch (Red Dragon) too but the same applies.

What's next a Stars and Stripes kilt?

Call me old-fashioned but to me it's a disrespect to the individual flags concerned. And I don't think they look good anyway.

There are much better ways of expressing patriotism such as a Saltire on the top of hose or a flag badge on jacket or headwear.
