Open the Mod Podge and dip the medium paint brush into the solution and paint a very thin layer on the inside of the seashell. Don't use too much Mod Podge. You only need a thin enough layer to hold the tissue paper at this point. Decide how you want to place the tissue paper design on the shell.
Start by practicing the arrangement by placing a few rows of seashells on the foam wreath. Working one seashell at a time, add glue to the back side of each seashell and hold in place until glue sets. Continue working one row of seashells at a time.

Gorilla glue is a more versatile option than E6000. It is because the E6000 can attach glass to glass. But Gorillas can stick not only glass to glass but also glass to wood, metal, and plastic. If you want an instant repair to attach glass to glass, choose E6000.
Both glues are great… I'd recommend Gorilla Glue if you hate foul odors. I would consider the Original brand if it's important for your project to be waterproof. I would recommend e6000 if you're looking for a tough as nails adhesive but don't mind the above minor caveats.

Fast bonding – Super glues bond extremely fast compared to other types of glue. The speed of bonding is usually measured in seconds and this depends on the working materials and the environment. The bond tends to be faster in environments that are warmer and have higher humidity.
Generally, an epoxy adhesive is used to bond items that are under greater force. Super Glue does not have as many uses and is used in smaller doses. The basic epoxy vs glue comparison is that Super Glue is used more in crafting, doing quick fixes around the house, and joining together small parts.
