I made two versions of this craft, one fully covered with the broken seashells and one partially covered. To make the partially covered jar I used painters tape to section off the part that I wanted to be exposed. This isn’t necessary but it helped make sure I had an even line.

To make the jars apply a generous amount of decoupage glue on the mason jar, working in sections. Allow glue to fully dry before turning to another section or else the rocks will slide off. It takes about 20-30 minutes for each side to dry. Another tip is to make sure you have a single layer of the shells so that they adhere to the jar well.
Once the mason jars were covered I tied twine around the mouth of the jar and added a tea light inside.
I have to say that I was really impressed with how well the American decoupage glue held the shells in place. Plus I like that it’s see through so you can see glimmers of light peeking through the shells.
