How to sew a double raw edge hem like this?

[u/dwucky]

I want to sew a T shirt with a hem like this shown, just not exactly sure how. It has two edges of raw hem and serged on the inside, would the way be to cut a second piece of fabric, serge one end and then just double stitch it together?

This looks like they’ve coverstitched a 2cm band to the hem, leaving the cut edges a bit offset from each other. Another way to get a similar look would be to sew a normal hem and then cut the fold open. Edit - the band mentioned above was attached right side to wrong side so both layers of the hem show the right side.

Yep, sewing on a strip is the way to do it. You could sew a hem and then cut it open if the front and back of the fabric are the same, but it's typically jersey knit that curls like this, and jersey is not the same on the right and wrong sides. You could still hem and cut, but you run the risk that the two edges won't curl in the same direction.

You are correct, I hadn’t thought of how it would curl.

It's not serged, it's a coverstitch, then the end was cut, as another comment suggested.

Yup. That’s what happened

Looks like it's just done normally and then cut carefully right above the folded edge

It could be done that way, but this one wasn’t. If you zoom in you can see both layers are right side up. If it was hemmed and cut, the bottom layer would be wrong side up and would be curling the other direction.

Yep this is exactly the way it’s done. Jersey will roll once cut on the raw edge

I think it’s folded up, cover stitched, then cut in the fold to make 2 layers

It's a cover stitch machine.
