I visited Dunkeld quite a while ago and really loved the tartan in the picture 'The Macdonald children' by Jeremiah Davison. (Pictured below.)
Now, as far as I know no-one has been able to identify it as being any actual tartan. All they can say is that it is similar to both the Macdonald, Lord of the isles ancient red and the Macdonald of Sleat.
Now, I'm getting a Macdonald, Lord of the isles for my wedding, but I'd be interested in getting one in this unknown tartan, too.

So my question is, how do I get someone to even weave it for me let alone make a kilt out of it?
