Canvas and materials

[Offgridyurt]

Hi. I’m building my first yurt. It’ll be 14 feet. I’m curious If anyone has a good reliable company where To purchase treated canvas. Which weight is Most appropriate. It is such a huge expense!

And also curious if any companies sell the plastic bubbles for the centre ring. I could easily include a soft vinyl, but the hard plastic rings have a nice look.

Does anyone have any experience make inner wall isolation from raw sheep wool? We live in farming area, so access to sheep wool.
