My daughter and son in law took a trip to Iceland recently and brought back a hand woven scarf. It even had the name of the weaver on the ticket.

At one time I made similar scarves on a toy loom - but a simple tabby weave, the Icelandic one is twill woven. It is a soft weave, not like kilting cloth.
You might be able to discover the price online, the bag shows a website www.handknitted.is the ticket on the scarf has Scarfur.is.

The scarf is just under 12 inches wide (it is going to be metric and 30cm of course - yes it is) and the length including the fringe is 80 inches - the threads might have been measured out to 81 inches as the fringe is twisted and knotted. Finished length of the fringe is 2 and 1/4 inches

With expensive fibres such as cashmere removing the weft to create the fringe could cut into the profit considerably.

I am not sure that a mill with a main output of 60 inch wide kilting tartan would be the best source of 30cm strips - particularly in different tartans - just the cost of warping might prove prohibitive. Mills usually work with wool or man made fibre yarns - luxury yarns would not really feature in their normal output. Kilt material uses fine yarn but the scarves I made and have been given are soft and fairly thick yarn.

I just remembered a weaver in Ringwood - Hampshire - he used to make scarves - long gone now (it gets to be quite irksome realising that the people most dear to the heart are mostly long departed this world) also made pieces of Kevlar material for the Police riot gear.

I suppose the obvious question is have you considered setting up a loom and making the scarves yourself?
