Scotweb lists wool tartans in IoS by Lochcarron and Marton Mills. 16oz MM Jura is not listed there but I know is available for about $55US per DoubleWidth (DW) meter from other vendors. Lochcarron is about $10 more per DW meter. 13oz MM Bute is on Scotweb for about $36 per DW meter, and 10.5oz MM Glamis is on Scotweb for about $28.50 per DW meter (Lochcarron is about twice this price). Marton Mills does not list it on their website, but are supposed to be the sole manufacturer of IoS in 11oz PV (polyester-viscose synthetic), which is listed as available at Scotlandshop.net at around $28 per meter DW. Scotweb prices are assuming you use the xmarks discount by entering their website by clicking on their advert top right of each page. Then you would have to add shipping, and VAT if you are in the EU. So the Marton Mills PV is not really any cheaper than the MM Glamis 10.5 oz wool. For a womans skirt or shawl I think the 11 oz material would be fine, depending on how you plan to use it. I have no knowledge as to color matches between the various versions within MM or between it and Lochcarrons fabric.

It is a beautiful tartan but legally registered and copyrighted so "copy cats" are not generally available, except for one god-awfully neon bright one called "Bright Skye" by those vendors that sell stuff made out of it. Not even close to the original.
