Ring bases, pendants and glue.
Step by Step Tutorial
Step 1: Glue the flat surface of the ring. Put an even layer of glue on the surface.
Step 2: Grab your chosen pendant which you want to be the top of your ring. Place it carefully on top of the glue-covered surface of the ring.
Step 3: Hold the two parts together firmly until the glue dries.
Step 4: Size the ring to fit you. Wear! :D
Simple as that! Enjoy!
P:S: If anyone would like me to custom make a ring for them, please comment on this post with what you would like + your email address, and I'll do my best to get one out to you for just a few dollars (NZ).
