I ordered Tartan material a little over a year ago from Marton Mills. They had the material in stock already, so it did not have to be woven. MM were very good in the communication department, with most of my e-mails answered within 24 hours. I did phone them to place the order and they were very helpful and friendly. I know prices have gone up slightly since I ordered, but with exchange being what it is, they are still a very good deal.
I was very happy with my transaction and I love my kilt that I made from the material.
Good luck with your order,
Sara
