Making some paper lanterns, need some help.?

So I'm throwing a Tangled themed birthday paper and I plan on making the paper lanterns. One problem, I'm fairly sure tissue paper is highly flammable. (Is it?) I know some people have made them out of rice paper but isn't that highly flammable too? So are there any easy to make alternatives or is there something I could use to make them less flammable? Or am I just full of crap for thinking the paper could burst into flames at the slightest hint of a flame?
