Here's a cheap, easy, and fun solution to your camping shade structure needs! The whole thing will cost you around 200 dollars and an afternoon's worth of pvc cutting. The result? a 12ft diameter, octagonal yurt that fits into a snowboard bag for easy transportation. I used a parachute ($60 included in the total cost) to cover it which works great as far as size however it is not very breathable so rolling up the sides helps during the day.
Now the fun! because it's so cheap to make, spend a little time on paint (helps with keeping the various parts organized). Also, the roof is almost 10ft in the middle leaving plenty of room for hanging lights.
Detailed plans coming soon!





































You're also increasing your costs and decreasing your portability significantly.
It may cost a little more, but it certainly looks more resiliant, and the step by step instructions seem to be really thorough. Comes with pictures.
