This is the bag before felting.
It is Patons Classic Wool in several colors, Brown, Russet, Chocolate and Old Gold
This is the bag inside a pillow case in my washer - the next picture I've opened the pillow case to check the felting process.
After I remove the bag from the pillowcase, I hung it on the washer lid to show how it looks after wash and rinse.
This is right out of the felting process.
