Yarn Tests for a New Tunisian Crochet Filet Design

I did two kinds of yarn tests for my new Tunisian crochet filet scarf: for tutorial close ups, and for a warm winter version.
For the first test, I’ve learned to take three things into account: the yarn’s plying, color, and thickness.
I didn’t know what to expect for the winter test because traditional filet lace has mostly been a cotton thread kind of crochet project.
Tunisian filet isn’t traditional, though.
