I've got a wonderful coat, the hood however is too loose. When I google for tutorials for how to adjust a loose coat hood I get nothing relevant. The hood is attached by poppers, so one idea I had was to buy some more poppers, but I've never used poppers (snaps? I don't know what to call them!) and am scared to make a hole in the coat fabric.
Do you have ideas either for how to do this or for better search terms for google?
