Ha, Oakleaf, I have those Acorn slippers. In fact, I am on my second pair. I can't believe I wore cheap, terry slippers for so long. I put them on as soon as I get in the house.
Yea, I am never quite sure what to do with the sewn together pockets, on let's say a nice pair of wool pants. I also thought it was for when they were hanging on the rack. Then, if you snip the threads, they look funny and gap.
