Apply Mod Podge to the top of the pumpkin using a paint brush
Lay the moss onto the top portion of the pumpkin, apply spray adhesive on to the moss & let dry
Hot glue small portions of the succulent on the top of the pumpkin until the moss is covered (or uncovered) to your desire & let dry *Want this to be a Halloween party exclusive? Add some cotton ball spider webs! Or, add bittersweet vine for a perfect Thanksgiving centerpiece.
Spritz with water once a week to keep succulents alive (I use a squirt bottle)
