I don't allow pop-ups. I went to his Photobucket gallery instead.
He has a 3-man silnylon tipi in white, with a stove jack, I like. These are called "hunter's tents" in Montana.
The lack of "floor" and stove jack are for cold winters.
The wyoming guy told me, in a PM, he uses an additional coating on the silnylon, no doubt, making it stronger and more stable.
I saw his posts over at WhiteBlaze.net and sent PM's.
I know I want one, but it will have to wait. It is not cheap. However, it is not expensive as the Kifaru tipis.
Kifaru tipis are also set up for use with a stove for heat.
The wyoming tipi has two doors, with double zippers, so the top can be ventilated. It is an excellent design.
The bottom of the tipi, in winter, has snow up against the bottom. Here is a picture of the one I like.
I want to use it with the TiGoat 2010 Vortex Cylinder Stove, a titanium stove.
Here is camo, but I like the white one for snow.
The polyester 3-man is very reasonably priced, and resists mildew. He said he sells a lot of the polyester tipis.
If you made a circular tipi, you take a rectangular tarp with the length twice the width and draw a semi-circle.
More poles, more circular.
The wyoming tipis have a loop to hang it at the top on a rope or use one center pole.
