Pop the primer out of your shell and cut a section out of your hull down to the brass wide enough for your beard-s to slide in to. Insert a piece of leather into the primer pocket and the crimp end of your shell having a loop shaped like a triangle above the shell, make leather as long as you want. You can tie the ends of the leather together and then slide the knot into the brass section of your shell to hide it, you can also thread your spurs on to each end of the leather before tieing your knot. If you dont use a knot to secure the leather thats ok cuase the next step is to insert your leather ends into each end of the shell and apply hot melt glue to hold the ends then 1/2 fill the complete shell with hot glue and slide your beard into the slot you cut then fill in the gaps with hot glue. Don't worry about getting to much running out it cuts off easy once dry. Hang it up for everyone to see!
Good luck
