Handwoven fabrics are wonderful , but I'd urge caution with using them for traditional kilt making, most tradtional(commercial) kilt fabrics are relatively finely woven and usually with very "hard" thread.It is partly this fact that creates a very stable fabric with hold the pleats and not distort. However if you were thinking of a "braveheart"kilt(!) then a hand woven cloth would be much more in keeping
