I was just wondering: how can you differentiate between fabric weights...say, 13oz. vs. 16oz.? I recently purchased a kilt from Scotland, made specifically for me, and it's a 16 oz. However, when feeling it, I honestly can't tell the difference between it and my other kilts, some of which are 13oz. and some are 16oz. They all feel the same to me; my fingers just can't make the tactile difference. Is there another way, other than feel, to determine whether a kilt is heavy or medium weight?
