How do you say knitting in French?

It depends on the context! First of all, it depends on whether "stitch" is a noun or a verb.

If it's a noun:

- "un point" if you're talking about sewing fabrics;

- "une maille" if you're talking about knitting;

- "un point de suture" if the context is medical (stitches following surgery, etc.);

- "un point de côté" if you're talking about a sharp pain in your side (e.g. after running too much).

If it's a verb:

- "coudre" if you're talking about sewing fabrics;

- "suturer" if you're talking about sewing up a wound.
