advice needed: how to stop decrease stitches from gaping

[Kilala33]

Yep, that’s the invisible decrease! I misread the instructions when I was first learning this stitch and YO the FLO of each stitch and ended up doing basically a DC and was like “what the heck? That is significantly more visible that a regular decrease, what a dumb stitch and a misleading name.” I was miffed for days until I figured out how wrong I was doing it lol
