This afghan is used several times at the beginning of 1840, both on Daniel's bed in the Tower room and folded over the back of the sofa in the drawing room. If I remember correctly, they never actually use it on anybody in the drawing room, and then after a while it's no longer seen on the sofa.
It also is seen in Daphne's room in episode 1129, before she comes to live at Collinwood.
