Is there a right way for an asymetrical tartan?

[RockyR]

SNIP... but are you saying that this is not so?

Correct... it is NOT so.

Small point of clarification that is my understanding (I MAY be wrong, but this is how I understand it)... Asymmetrical tartan's do't "pivot", they repeat: ABCABCABC Symmetrical tartans pivot: ABCBABCBABCBA

Either way, the selvedge edge is not usually a pivot point, unless the math just happens to work out that way. Think of the WHITE line in Douglas Modern. That is the pivot point, yet the white line itself is RARELY (if ever) used for the selvedge edge. Typically, it is a darker section of the tartan (at least 1 CM 'tall') that's used for the selvedge (if possible) and ESPECIALLY when it's a TUCK selvedge (like Lochcarron, MM, Batleys and about 10% of HOE's cloth). This way, the part of the cloth tucked back in won't show nearly as much.
