I'm working on a surprise decoration for my girlfriend in the guest room, and I need to lock the door from the outside without any obvious changes. She doesn't usually go in there, but I want to ensure it's completely secure for about a week while I set everything up. Any clever ideas?

Honestly, just be upfront! Let her know you're working on a project that you'd like her to avoid seeing for a week. If you hang up a sheet just inside the door, it’ll keep the surprise intact if she accidentally opens it.
You could put a door jam on the inside and then sneak out the window when you need to. It’s a little unconventional but it works!
This will definitely do the trick!

But wouldn't she wonder why you're not using tools? You could just swap the knob for one with a lock—it’s a quick fix and would give her a working lock for future guests!
