I know the pictures are really really shitty, but that's the best I can do without the digicam. I used a webcam. I'll get better pics tommorow and with it in the car. This one isn't perfect, it could use a little trimming, but it looks decent and does what it's supposed to.

Materials and Tools:
Screw Driver
Hinges
2' x 4' x 1/4-1/2" Board
Saw
Carpet
Procedure:
Measure the distance between the inside of the hatch cover area (exactly where the cover will drop in). Measure the width. Cut the board to those specs. Place the board inside the car and outline for the area in which the cover will drop in the hatch, then cut it. Leave a couple mm's off the edges to compesate for the carpet. You also have to cut a small peice for the latch thingy in EG's, dunno about any others.
Or you can use cardboard and then trace it onto the board.
After the board fit's nicely into the hatch area, cut it in half, longways if you want it to be able to fold. In my case I cut it about 10 inches or so, so I have the little folding thing. Put the hinges on the top of the board (they're going to be removed, but it makes it much easier later). Remove the hinges.
Now to the carpet. If you are doing it the same exact way as me, then cut the carpet about 2 inches more than the area of the board. Staple it onto the board tightly. It's pretty simple, staple one side, then pull the other to make sure it is flat on the top. Put at least one staple in each of the shorter sides first, make sure it's tight though, this will make the longer side easier, do the curves last. Leave some space where the holes for the hinges are though, so you can poke a hole through the carpet through them. After you've poked the holes staple the rest and be sure it is nice, tight and flat on the top side. This is the same for both sides of the folding hatch. You can also cut the carpet so it covers the entire area of the board, back and front. This way you only have to have one peice of carpet. You can also glue the carpet down and remove the staples later for a better appearance.
Now, replace the hinges and fit it in there. Be sure everything fits correctly and your done.
See that was simple.
