This is not cherry-coloured silk twist, ^ this is pink pearl cotton, which I got, of course, at the Thrift Store.
But as I researched what in the heck pearl cotton is, I learned it is cotton thread soaked in a chemical under pressure ("mercerized") to make it swell round, the roundness adding luster because the light bounces off it:
thus mimicing silk!
And "twist" just refers to the number of turns required to hold the fibers together.
I got all excited about this because I get a thrill when things connect up, and what this connects up with, in my mind, is Beatrix Potter's Tailor of Gloucester.
Have you read it?
It's my favorite by her:
A tailor releases some mice from under teacups where his cat has trapped them. When the tailor becomes temporarily too ill to work, the mice repay him by sewing the last remaining details on the mayor's wedding waistcoat that will change the fortune of the poor tailor:
"one-and-twenty button-holes of cherry-coloured twist!"
And... "For the lining of the coat there was fine yellow taffeta"!
