Thanks for the suggestions and the link guys, all good ones.

Sage grows everywhere here so there's plenty for me so pack into whatever "dye tea" I can brew up.

The UK white workmans has been died many times and isn't treated that I know of...seen a few dyed ones on the board.

I have an old hippie friend down the road that does tie dye tshirts still, was gonna have him do a rainbow tie dye until my brain hooked on sage.

I've also seen a local book on how to dye the Navajo way...right down to some dyes ya gotta pee in so the ammonia does something... a bit extreme. But the Navajo book is about dying wool yarn before they weave it into beautiful rugs...guessing it would still work for already woven heavy cotton.

Main thing I'm after is "local color." A kilt that matches the colors of the canyonlands. Other idea was doing "dirt dye" but I don't really like the color the dirt dye t shirts they sell tourists are.

Guess I could start, as someone suggested, and dye an old tshirt in sage tea and be sure I like the color...

Guess I'm most concerned about trashing an expensive kilt not knowing what I'm doing...

Thanks for the ideas and support.
