Gotta tell you about the time I made a bum shot and wounded a deer, then went to reload before tracking it down. Opened my bag, and no patches. Zero, zip, nadda. Got the deer, but it woulda happened quicker if I had more confidence or experience in shooting bare ball from a rifle. Got within 20 yards to do the deed, but could have ended it an hour earlier if I'd had a patch. Didn't occur to me till later that even a hunka tee shirt or my denim pant leg would have been better.
Prior to that, my patch box held all sorts of odds and ends.
Now it holds a few less odds and ends, but I keep it all quiet with a few greased patches on top of the pile before closing the lid.
