Today I have a no-sew, no-glue, no-tape, no-staple alternative utilizing some simple folds to make a self-locking envelope. You can use it to package soap, jewelry, potato chips, a book, pretty much anything!
Flatten out the body of the bag and cut it in half. You can make two wrappers with the one lunch bag.
Try using this same technique for wrapping up larger objects in larger pieces of paper. I use old calender pages, posters, shopping bags, thin cardboard, and even fabric or plastic. I am chronically trying to see potential uses for all kinds of “trash”. This is a great way to make your own shipping container sized perfectly to fit your package. This way I don’t use any more packing material than absolutely needed. I pad the object safely, and then wrap it up. A little tape is all that’s needed to secure this package. Try rethinking how you see “trash” and see what you come up with! (-:
