In this tutorial, we learn how to apply a neck ring and plug on a reborn baby doll. First, attack the neck ring to the doll head by pulling the vinyl onto the lip using your fingers. You will need to use your hands to push the inside of the neck through the ring. This will take a lot of pushing and pulling. After this, you will need to attach your plug. First, place it into the neck of the head to make sure it fits. After this, stuff it with cotton and then push it back in. Now you will be able to complete your doll.
