Grist: How Close Do I Have to Get?


#1

Regarding Jillian Moreno’s post “Grist: A Secret Measurement for Substituting Yarn.”

Does the comparison need to be spot on or is there such a thing as “close enough”? Can there be wiggle room of a yard (or 6) per ounce?

I have this same question. I’ve been using this notion of grist ever since I read the piece in MDK and I get how the same weight yarns can actually weigh a lot differently, and in some cases the difference is so great that it’s clear a yarn is not a good substitute. But when it is less obvious, how much of a difference is too much? Is it 10% or 30%? Or should one note the difference and also factor in other variables like ply and twist or something I don’t even know about?
