Just yesterday I went through an entire drawer of thread, purging spools with nothing left, tidying the spools and arranging by color. It was then a surprise to myself that I decided that my favorite thread is Coats & Clark Dual Duty. It has never let me down. I even have an entire thread cabinet of another brand with about 160 spools, but I find the Dual Duty to be a better thread and will choose that brand first from now on. The article is very interesting and I'm looking forward to learning more
