I finished knitting my slippers for this year, about 2 weeks ago. Finally, after 2 washes in the machine (could curse myself as I did them on too low a temperature the first time), they felted.
They were stretched onto my feet to shape them, then very carefully removed and left to dry. You usually need to re-shape them after removing as the back part goes out of shape!
Also, just finished and washed another dishcloth.
