Several years ago, I had 25 meters of Red/Black tartan woven by www.houseoftartan.co.uk
You can read about that project here:
I no longer have any material and I have no plans to obtain any more, but the pattern is still on file at house of tartan.
The pattern I used became known as "Menzies McLeskey Adjusted in Black/Ancient Red in the 10 oz weight". I bought some decent used seat covers from S&S Preparations to use the vinyl.
If anyone wants to use this pattern, they are welcome to contact House of Tartan.
I looked into having some Green/Black material made, but I had a difficult time matching the shade of green and I did not think the market was large enough to justify my effort. If someone is close enough to send a good green sample to House of Tartan, perhaps they could match it.
During the project, I learned that the original material was printed and I was told about a company that will print material for you. It is based in the US and is called "Fabric on Demand" firstname.lastname@example.org
. I have not tried them myself and cannot vouch for the quality, but that is an option.
