Put a dot of glue on the flat side of the glass bead and attach to the Terracotta pot.
Continue to place the beads all the way around the pot.
Finish gluing the beads all the way around the pot until you are happy with the design. You can use different size beads to make a different effect on the pot.
You don't have to go all the way down with the beads. You could do just the row at the top. Do what you think looks best.
Once you are done and all the glue has dried, remove any excess glue strings that were left behind.
You can put a plant in this pot when you are finished. A cactus would be a great idea. If you don't have any plants to put in the pot, set it on your desk and use it as a pen holder.
