...What exactly is contact paper; where can you get that at?...
I see no one has replied to this ? - sorry about that

It is shelf liner. It can be purchased at many grocery stores, places like Wal-Mart and even some $ stores.
It has glue (is sticky) on one side; either clear or printed on the other and is plastic.
NOW: some people has contacted the company and have been told not to use it for this application ........ they are covering their butts...... the reasoning given is that when the cake is cut tiny slivers of the plastic can be served. Well that can happen with *ANY* non-edible covering (aluminum foil, freezer wrap, etc) so I cannot agree.
Use your own judgement knowing the above

For years (and still I think) many people has used florist foils. They certainly are NOT the best choice as many (if not all) have lead used in making them.
A safe way is to cover your board with *whatever* you want - including fabric, foils, contac paper etc) , then put the cake on another board the exact size of the cake, which is then glued to the fancy covered board.
