I heard back from the band and they can forward me details of the suppliers they use. He did also say that the tartan was under a copyright owned by himself. Though he has no problems with me using it he was surprised that it appeared anywhere else.

I'm not sure how copyrighting works with tartan but I'm surprised I found it on http://www.scotweb.co.uk/tartan/Shef...r_weight=Heavy on sale.

Still, I'll let you know how it's going and take your advice.
