Swiss darning, integrated.

"Do you know what's luxury? This patch is.  They make it look casual on a 30 second insta-reels...but this took time, because it wasn't cheap.  I'm ok with that, though, because I can see the value. I see where my spend is, it's on my jumper. That's luxury."

Swiss darning on fine knit with integrated stitches in three colours.
