Straight down the middle.

I'm making a hand sewn 6yd 11oz Black Watch at the moment. I own two ther tartan kilts (Hunting McLeod SWK Standard & Irish National SWK Economy), though I have no tank. I may eventually make a tank for myself, but it'll cost a bundle. I'll do it in the $65/yd Clan Cian (Carroll) tartan.

As for more modern kilts... I have on that's made from Advantage brand camouflage duck, I have a khaki duck waiting to be turned into a 6 yarder, I have a Solid Black SWK Economy, and I have 5 yards of desert camouflage waiting for the needle. I also want to get a Saffron SWK Heavyweight, a SWK Nightstalker Standard, and a black and a caramel UK Workman.

Boil it down... I wear kilts. It's as simple as that.
