F.A.Q. We have had many emails regarding questions about their lavvu that they are about to buy. Here are some of the common questions and answers: How many poles do I need for my lavvu? I am cutting my own poles. How long do the poles have to be? I do not have access to a forest. How can I get poles for my lavvu? Will the retractable aluminum poles that you offer work on larger lavvus? There is a smoke hole at the top. How do I keep the rain from coming in? What kind of flooring is there in the lavvu?
