Once you got your box you also need to get some sort of cloth or some cotton balls for the padding since this is where you are going to lay your glass on when you sleep. I'll be using a red cloth that I also had laying around, just put that to the side for now.
Now strip the box of its insides but keep the part with the phone like indent ( where the phone sits on when it greets you as you open the box for for the first time) we are going to use that later, you can toss the rest if you wish.
Now the that's done let's move on...
Step 1: The Base
Now that you retrieved that piece and smell like death we can continue,
What you want to do is flip that puppy over so we can get the back side upright, this will serve as the smooth bottom that the cloth will sit upon. Ya just nudge that in there nice and easy so you don't bend or get a dent in it.
Got that? Good let's move to the next step.
Step 2: The Upholstery
What you can to do is fold it up, whoa hold on there don't cut it! By folding it you get that extra cushioning that will fill the rest of the box up.
We good? Awesome, let's go to the next step
Step 3: The Stuffing
All good? Awesome!
Step 4: The Placing
Now you don't need to do as exactly as I did here, you can mix and match various materials that suites you. This is just what I had laying around and really just needed something simple, so be creative!
