I haven't made a kilt in too non-traditional of a material. Yet. I've done PV, canvas, and denim so far. I am thinking of silk though. Denver fabrics has a very hefty silk (about 7 oz. per square yard) that I think might be nice, but I haven't checked out a swatch of it yet. I've also been thinking of a moleskin or ultrasuede with silk or satin contrasting inner pleats. (Somewhat like PK used to do.) My kiltmaking activities are on hold however, until I can get a little ways out of the hole I'm in right now though. Great thread, I hope to see some interesting stuff in this one.
