Last night I somehow had chewing gum on the back of my shirt, and before I knew it was there, I leaned against a throw pillow on my couch, getting gum on the pillow too.
How would you remove the gum?
NOTE: This is different than the existing question of how to get gum out of a carpet, since carpets are typically stuck to the floor and are big. The fact that the shirt and pillow are "free" and small results in different answers (like the one that worked for me; see below!).
