The quilted yurt I saw was a project by the Wisconsin Museum of Quilts & Fiber Arts. You can read more about the project and the current Yurt Challenge at this link.
The current yurt has been on display at the museum and other venues. You can see that it isn't large, but is very nice and cozy.
The quilts both inside and outside the yurt are all very different and fun to look at. I think this is really a doable project, especially if you know someone who is handy and can build the frame for you. All you would need is to cover it simply with fabric and add your own wall quilts. Or, why not have your own challenge and invite your friends to create a quilt? If that sounds like something you would like to tackle, you can find yurt building instructions at this link.
