I always double check my label to make sure all is correct and then cover with clear packing tape. If you are sending breakables, pack in a padded plastic bag and then TIGHTLY pack with popped popcorn in an oversized sturdy box. Cheap packing material that travels well. My husband repairs violins and other stringed instruments and that is his packing material of choice and it has never failed to get to the owner in reasonably good shape. Always label FRAGILE on all sides. Do not label quilts as "quilts", but as bedding materials so thieves won't be interested.
