I don't usually put notice of this stuff here, but because of what they happen to have on sale right now, I thought I'd pipe up....

16 ounce wool, Ulster, weathered and 16 ounce wool Maple Leaf tartan are their current offerings at $30/yard Canadian, which is about $24.67 per yard in USA dollars. So if you're dying for your Tank in the Maple Leaf tartan or the Ulster, here's your chance. That's about $100 for enough high quality tartan to make a serious serious knife pleat kilt, or for $75 you've got enough for a double box pleat a la the Lady Chrystel.
