I think it depends on if they are gaining or losing moisture while going stale. If they are softer, do this. If they are hard, stick an apple slice or two in the bag with them. This works for weed, too, if you don’t like how dry it is.

But mostly seal your bags as well as you can when you set them aside. Bag clips help. It also helps to remove as much air as you can before you close it.
