Oklahoma State University Tartan

[tripleblessed]

The OSU tartan was apparently woven in 2007 by Pendleton for scarves or
blankets for stadium use. The bookstore site did not list fabric availability,
but a fan forum linked an article about it, and the comment to contact
the office of licensing and trademarks. That office lists Kurtis Mason, at
kurtis.mason@okstate.edu Message sent about your interest,
suggesting post here. You could e-mail him direct.

Happy hunting.

All that information is helpful... but the OP did ask where he could go to get one. Rocky at USA Kilts would be able to get the material I would be willing to bet, so long as you have the appropriate permission! Matt at the Scottish Tartans Museum as well.
