Does anyone know how much wool shrinks when you wash it?
I'm using yarn with 20% wool. How much would this muffler shrink if I washed it?
(I just want to make it smaller, it's not dirty or anything)

What are the washing instructions on it? Can you put it in the wash? Or does it say hand wash?

umm I'm knitting it so it doesn't have instructions XP

Then how do you plan on shrinking it?

By washing it?

It shrinks a lot and gets all disgusting. :selfvomit

Even if it's only 20%?

what's the other 80%? polyester?

since you're in the process of knitting it yourself, make a small swatch, wash it, and see how much that srinks
