Step 1: Cut Your Cardboard
Cut around it and add a bottom , hot glue the forms together , remember to add some sort of structure to it And add it to the middle so both
Cardboard and tombstone stand up by themselves,
Add sand for weight use ziplock backs if you have them , if you don't your old Walmart bags will do. Add enough to make it heavy so it won't fly around everywhere.
Now it's ready to "glue" together take your paper mache mixture and seal it all around the sides make sure there no holes,
Step 2: Drywall Paint and Seal
Happy hauntings !
