We had no mailing bags the right size. I put the book in a large bag, folded it in half, sealed it, and wrote my friend's name neatly on the bag. My husband taped the edges tightly, so it would not split en route to Virginia. He is a thorough taper and wrapper. When he wraps a package, it is safe. I left on errands, confident the book would arrive in good shape in a neat package.
