Sew vs weave

Is there a difference between sewing seams and weaving seams?

There are different ways of joining seams. You can use sewing techniques like a running backstitch on knitted garments. You can also do most seams with a mattress stitch, which creates an almost invisible seam and which might be thought of as more of a weaving technique.

Where can I find out how to do these the running backstitch or the mattress stitch? Thanks

There’s a tutorial for back stitch here and one for mattress st (on this website) here. Hope the seaming goes wel!
