Here is the giant dog bed (30" x 45" x 3") that I slaved over for the huskies and they don't appreciate it in the least! Contrary to what the above pictures may have you believe, it is rarely used. Both pictures were posed and after it was over they got up and went about their business. It has a batting wrapped foam insert and zippered cover for easy washing. I used fabric from Joel Dewberry's ginseng line.
This is by far the best tutorial I could find on making your own bias tape (piping).
