So, my wife said she may want to attend a religious festival next year. I said that was fine. We do not have a tent anymore and it is a camping event. This allowed my little brain to start whirling and grinding on solutions along the lines of inexpensive, relatively. We did attend a mini-rendezvous a bzillion years ago in northern Maine. We had to opportunity to stay in a lodge (tipi). Since then I have desired to have one. They are, however, cost prohibitive to me. That is where the Web comes into play. I am thinking I could make one out of a big tarp or Tyvek. The problem being I could not find any plans for one. Then it occurred to me a tipi is a cone. I searched the aforementioned Web and BINGO!!, a cone calculator. Problem solved.
