Felted Bag: IN the Washer
I stuffed it full of plastic grocery bags before washing, thinking that would help the front and back not stick to each other, but of course all the bags did was come out and get washed with the rest of the stuff. ;p
But with the bag all stuffed with bags, I thought maybe the stitches were big enough.
I used the hottest temperature, the smallest size load, added Dawn dish detergent because one blog said Dawn specifically worked very well to help felt, added a towel and a pair of jeans, and let it go through the agitation cycle once, then the whole wash cycle again.
