Anyone make your own package tray?

I made one for my duster. I went to the hardware store and got a 4x8 sheet of fiber board,if I remember correctly it was about 1/4 inch thick. I used what was left of old one to trace it and cut it out. Then just got material that matched interior and used spray adhesive and glued it on. Do not have any pics because car is in storage for winter. It turned out good.
