I use Danville 6/0, 3/0 and flat waxed. I know that Denier may be a more universally reliable way in which to measure thread thickness. I noticed recently that the Danville Flat waxed is also called Denier 210. I also notice that there is a Danville Denier 140. I am not familiar with that thread. How does the thickness of the 140 compare with 6/0 and 3/0? Are there other differences, such as thread composition? Twisted/untwisted?

Thanks.
