A fabric-density description can become ambiguous when its direction or unit is omitted. Keep the construction information understandable to the person comparing materials.
CottonWorks describes woven construction through distinct warp and weft yarn systems. CottonWorks — Weaving Basics.
Read the supplier's notation
For a lining comparison, identify which value refers to each direction and what the stated unit means. Do not compare isolated numbers from different notation systems as though they were equivalent.
Keep the complete specification
Retain the relevant fibre, yarn and finish information with the construction description. Density alone does not establish hand feel, durability or suitability for a finished character. Use the actual material and appropriate evaluation to resolve those questions.
