One of the first things I wanted to do when I got back to Florida was go to a weekend Flea Market we visited last year.
One of the vendors had serger thread that I felt was of decent quality for a serger. The reason I didn't buy any last year was the vendor required cash which I didn't have on hand.
The label gave no information about the thread. So, one has to go by feel, sight and the strength to break it.
Naturally, I stocked up. I had run out of red, so I doubled up for my 4 thread serger. I am about to run out of black. Can't believe after all these years, I never had pink. I went ahead and grabbed the only 3 yellows and the one U of KY blue.
