Hey Mallard,
I read your post yesterday but wanted to think about it awhile so I never answered.
I suppose the first place I would look would be a butcher. Cool net stuff is sometimes used to wrap meat as well, maybe they have a source.
Second place I would try would be a craft store. Sometimes people use nylon netting for wrapping candies in for wedding banquet tables, or to use in scrapbooking (wife's biggest hobby) or other crafts.
Third - by a whole bunch of marbles - sometimes they are sold in net bags[

] If your kids are too old you can ship the marbles to me[

] or donate them to a charity.
Anyway I was serious about the first two. What I have found and you probably will also, is that it is really tough to keep the heat to nothing in the smoker, so over the course of the 4 pucks, you get BS rack marks on the bottom of the cheese. The cool part about that, is that if you are able to "sack" your cheese first, you could smoke the cheese in the sacks by hanging them - then the only pattern you would get is the one you are looking for! You would not have to try and pattern the cheese after smoking, the smoking process will do it for you.
I didn't know where to inject this part, but my idea once you find some netting, is to wrap your cheese so that you gather all the loose ends together to form a "top" and then use small hog rings to pinch it together. I think that would look the most like a finished professional product.

I think the cheese would be a great one, I'm going to start a new thread for everyone else to give us some ideas.</font id="red">
