I have thought of the accessories part, sporrans would really be the only really needed part. Hose, we march on a parking lot for everything except games and competitions and regular socks are very much better than knee highs in the heat. without hose, who needs flashes? really I have some, and I don't have any real hose. I just look like an idiot.

now here is the cool part, for kilt pins, I got this idea.
I have a source for rare earth magnets at a pretty good price. now if I ordered everyone a wire trombone magnet like this:
and then just a rare earth on the underside of the outer apron.

I am really surprised too, the rest of the section is really stoked about it.
