Cut out the label you have printed to the same size as your CD. Cut a hole in the center of the label that is the same size as the hole in CD. To get a hole in the center of the label, place it on top of the CD and use a pencil to poke through where the hole on the CD is. Use scissors to trim the rest of the way.
Use a glue stick to evenly coat the back of the CD label. Make sure you go all the way to the edges of the label and that there are no clumps.
Place the label with the glue facing up onto the CD spool.
Place the CD with the data side up onto the spool and press it firmly onto the label.
Take the CD off of the spool and smooth down as necessary. Allow to dry completely.
