Any #3 lightweight yarn

I’ve always admired the timeless look of knitted pullovers but I can’t knit that well, hence came to the rescue Tunisian crochet.
So I wanted a simple construction, thick fabric, knitted look and a V neck vest for him.
Tunisian crochet is one of the techniques that I really enjoy. I love the knitted look you can achieve with this fun technique. And none of the hassle of knitting (no offence knitters!). It works up so quickly and is beginner friendly.
Also there is a companion video in size XS
