I use the same plastic things from wal-mart. I was going to use the dowels on the bottom to elevate it. They are bamboo skewers that have been cut in half. That way they are disposable.
It was Sailors post that sparked this idea but his sure looked nicer. (thanks Sailor) I don't think he uses it for 2 levels of cheese but for the small camamberts it should work. What I am not sure of is if it will be to humid with 4 cheeses in there. I think that could be regulated with the lid.
Thanks for the opinions.
