Anytime I knit a top with an armhole that’s a smidge too big (happens to the best of us), I fantasize about filling in the bottom portion somehow. Today I took a stab at it and I think it kinda worked!

And yes I know this is not the neatest work in the world. It’s a quick and dirty proof of concept. I’ll put my method in a comment below.

I CANNOT be the first knitter on earth to have tried this, so the reason I’m posting is to ask if anyone has seen examples, demos, tutorials where someone else has done this. I’d like to see how others have thought through this, what kind of math they use, etc.
