What you will need:
1 Clear Plastic Freezer Bag
Clear Packaging Tape
X-Acto Knife or Box Cutter
Step 1: Cut the Freezer Bag to Size
Place your iPod into the back at the bottom corner making sure you use the back side of the bag so the label isn't blocking the screen. Make sure it's in there nice and snuggly with the edges of the bag!
Proceed to cut around the iPod. Make sure you leave about 1.5 inches of slack on the vertical side and cut just about flush to the top of the iPod horizontally.
Next, tape the vertical edge of the back to the back of the iPod. Make sure it's not too tight or else you won't be able to remove your precious easily.
Step 2: Reinforce the Touch Screen
Don't fret if you have a bunch of bubbles! A good technique for eliminating them is to take your X-Acto and poke the bubbles from the inside of the case, just enough to let the air out. Once you've done that, just squish the bubble and it will be almost perfect.
Step 3: Bust Out the Duct Tape!
When you put the top horizontal piece on, make sure you have quite a bit hanging off the edge to make a flap so you can wrap it around the back side. Put tape on both sides of this flap.
Step 4: The Flap Strap
Pull it off the surface and stick it to the back of the casing near the top so the two double sided pieces are horizontal to the flap.
Take another strip of duct tape about 8" long and cut out a long strip about 1/2". Fold it over so that it is sticking to the flap on both sides.
Do a quick test to see if the strap is long enough to hold. If not, make adjustments accordingly.
Step 5: The Headphone Jack Hole
Congratulations! You have yourself a fairly rugged iPod case! I haven't drop tested it yet, but I do believe that is where this case is lacking. Have fun!
