when I read it I felt it had a slant against the Irish in Kilts and "Irish tartans". This my have just been the mood I was in at the time, but I still feel that way.
For what it is worth, the article was not meant to be "against" or "for" Irish kilts and tartans, but simply to tell the actual history behind the wearing of such, for the purpose of putting not a few myths to rest. Hopefully we have achieved that.

The Irish had long before that worn a belted garment that created a pleating effect. These were a saffron dyed tunic called a lein. To say a saffron(solid color) garment was worn in Scotland long before the Irish attempted to adopt the kilt is misleading. A saffron garment worn belted and down to the knee is definitely Irish, just not what is called a kilt at the time.
The garment you are describing is called a léine (essentially the Gaelic word for "shirt.") I suppose it had certain similarities to the modern kilt in that it was often worn knee length and certain styles could be pleated. However, it is essentially a very different garment. The léine is a shirt/tunic. The kilt is a wrap-around skirted garment.

The kilt did not, in fact, evolve from the léine, but rather from the wrap or mantle worn as an outer garment -- a brat or plaid.

Your post seems to suggest that you think "saffron" is the same as "solid color," which is not accurate. Saffron refers to the yellow color (supposedly from saffron dyes). We never made any mention of a saffron garment being worn in Scotland in this article. (Not that saffron dyed garments were not worn in Scotland -- they were -- but that is not in the scope of this article).

I did mention that solid color kilts were worn from an early period in Scotland, and I don't see how that fact is misleading. My reason for pointing this out is that in the beginning of the Irish kilt movement, all the kilts being worn were solid color -- so much so that many today assume the very concept of a solid color kilt itself is Irish. Many are unaware that there is a long tradition of solid color kilts in Scotland, and in fact the wearing of solid kilts can be shown to date back nearly to the very beginning of kilt wearing in Scotland.

So the use of solid color kilts is not particular to Ireland. Though certainly it is fair to say that the use of solid green or saffron is characteristic of Irish kilts.

When the Ulster tartar is mentioned it was probably
made in Scotland, which I have seen no proof otherwise. He was found wearing pants, BTW the Irish National, of fabric woven in Ireland.From what I remember most likely in Dublin. But of course it was added that "Ireland was at this time being settled heavily by Scottish emigrants, so it is at least conceivable that the cloth was woven by a Scottish weaver relocated to Ireland. That continued the feeling that the article was pulling everything back to a Scottish heritage.
What we actually wrote regarding the Ulster tartan was, "It was determined that the trews had likely been tailored in Scotland, but the tartan fabric itself woven in Ireland." This was not our conclusion, but the conclusion of Audrey Henshall of the Ulster Museum who examined the artifacts shortly after their discovery.

I was the one who added the comment, "It is worth noting that the Ulster region in Ireland was at this time being settled heavily by Scottish emigrants, so it is at least conceivable that the cloth was woven by a Scottish weaver relocated to Ireland."

This comment was not intended to be "anti-Irish," but simply to put the garment within its proper historical context. The fact that the garments were found in Ulster and can be positively dated to a period when Ulster was being settled very heavily by Scottish people, combined with the probability that the cloth was sent to Scotland to be tailored, means that we should at least consider the reasonable possibility that the cloth was woven by an Ulster Scot, or possibly worn by an Ulster Scot, rather than a native Irishman.

This is a possibility -- nothing more. The fact is we have absolutely no idea who wove the original tartan, or who wore the original clothing. That is why I wrote that "it is at least conceivable" and not "it is certain" or even "probable."

You say it makes it sound as if we are "pulling everything back to a Scottish heritage," and in a sense we are. For even those who were responsible for introducing and promoting the Irish kilt admitted that they looked to the traditions of Scotland for their inspiration -- that much is documented in the article.
