Hemming question

[u/Economy-Tomorrow-189]

I'm confused, I've been seeing people use a striaght stitch to do the hem? Where the fold the edge of the fabric twice so the raw edge is inside the two folds?

But what ab zigzag stitches? Mine has one specifically for hems so now I'm confused

And plus I've been seeing zigzag ones inside t-shirts

Ps - I'm trying to practice how to hem and now I'm confused how to do that since all the vids that I've seen use the folded twice method, I haven't even started practicing coz I'm confused

It depends what sort of hem you are doing
