I am knitting a sling bag with Red Heart Full O Sheep yarn (100% Peruvian wool) that I plan to felt in a hot wash. I would like to know how much I should expect this item to shrink. I'm betting on 50% but I'm wondering if anyone else has felted this yarn before and knows for sure. I usually use another brand and it shrinks about 40-50%. Thanks!

Haven't used that yarn.

I'd just keep an eye on it, stop the washer a couple times to check progress. Unless you have a front load washer, then well, whatever will be will be!!

If nobody pipes up with their experience, be sure to come back and post yours.
