When I first learned how to crochet I tried following the YouTube videos as closely as possible which resulted in everything I made having that v stitch. I remember absolutely hating how it looked because I was envious of people who made amigurumi with the x look lol. Eventually, I learned how to make that stitch round four years ago so I've never gone back to the v stitch which I like to joke it's a trauma response
I know and have uysed the Yarn Under technique and I know it can make a piece look 'cleaner' but I just CANNOT do it efficiently and quickly the way I can a standard Yarn Over. It's just not for me and the subjective gains in looks is nto worth the insane amount of effort I'd have to add to a piece I am making.
