I have been thinking about trying wood wicks, however, I read a thread that say's it could be a patent problem when selling them. I don't want to get caught up in any of that*shudder*. I saw a site on etsay that has them and they don't say "wood wicks" but they say "wicks made of a soft wood fiber" Do you think wording it like this keep's you out of trouble? Any help would be great. Thank you, Suzan:D
