STEP ONE:

Assemble everything you will need:

1) A Hershey bar in original wrapper

2) double sided tape

3) your custom wrapper

STEP TWO:

Flip the wrapper over while keeping the top at the top.

STEP THREE:

Attach 2 half inch pieces of tape to the bottom corners of the wrapper.

STEP FOUR:

Flip the Hershey bar over onto your wrapper as shown.

STEP FIVE:

Pull the top of the wrapper over the Hershey bar.

STEP SIX:

Pull the bottom of the wrapper up over the top flap and make sure the edges line up.  Now press the corners down to make sure the tape is stuck.

STEP SEVEN:

Marvel at your hard work!

Note:

You can roll your wrapper slightly around the bar if the front is not centered correctly after your assembly.
