It seems that this rabbi from Lodi, California, is laboring under the same misunderstanding as the one from Scotland who attempted to create an official Jewish tartan merely by registering it with the Scottish Register of Tartans.

A tartan becomes official as to an organization by being designated as such by the governing authority of that organization. E.g., the chief of a clan decides what his clan's tartans are. The government of a state in the US decides what that state's tartan is.

Simply registering a tartan with the SRT and declaring it thus the official tartan of X does not make it so, not by any means. Further, there is no governing body of all rabbis that I am aware of that could make such a decision.

It's unfortunate that the people at SRT don't make that clear to those who register tartans with them, rather than perpetuating these misunderstandings in their descriptions of these tartans.
