We have a great collection of pendant frames and domes in our catalog.
They are so easy to work with. If you want to share a photo or image you just need to make sure you size it according to the shape and pendant size you have.
You can use your dome to determine the area you will be featuring.
Once you have, you just press the clear dome onto the paper and trim it. The dome already has adhesive on the back side.
The image you cut now can be glued into the bezel.
I have a quick video right here showing you the technique.
