Piping bags are sold at most hobby and cooking stores, they are not expensive. If you need something for a one time use you can cut the corner out of a plastic bag large enough to mount a tip, or if you do not have tips cut a small hole in the corner. You will not be able to do a lot of design but you will be able to add some lines to your cake.
To make a piping bag nozzle at home, you can cut a small hole in the corner of a plastic sandwich bag or use a sturdy plastic bottle with a small opening. Fill the bag or bottle with your desired icing or frosting, then twist the top of the bag or bottle to push the icing out through the hole. This makeshift nozzle can be used for basic piping tasks in baking and decorating.
