Invisible decrease. YES! If you make amigurumi, it’s definitely worth doing. It makes the gap from sc2tog go away completely, which always kind of bothered me and I didn’t realize I could do anything about it.
But I can!!!
PlanetJune has excellent written directions on how to do it. I learn better by reading than I do by video, but I know there are videos on Youtube on how to do it- just look up “invisible decrease.”
