I know this has been discussed before, but I'm wondering if "advertised" "weight" of different cloths ( such as kilting tartan vs tweed) really means much?
In my searches, both on this forum, there seems of be a variety of ways of measuring "weight". If I find, for example, Harris Tweed advertised as 18/19 oz. per yd., double width, on one website, and what appears to be the same pattern, on another website, but only in single width, but advertised as 18/19 oz. per yd. - will the single width likely be the same "weight", or twice the "weight"??
Or, do I/should always ask, each seller/producer, exactly how they calculate the "weight" of their cloth , and then try to calculate how it compares, to compare "apples to apples"??
