Yes, I would love a free ZipTieDomes T-shirt - Adult size M or L.
I haven't made the 5/8 dome yet, but we've made the 3/8 twice. Attached are photos from the initial build in the park to make sure I made my measurements properly.
This past weekend we took it to a music festival in Southern California. The additional 3 photos show the construction and finally putting a parachute over it to cover. Unfortunately parachutes do not provide great UV protection - it got pretty warm inside during the hot day sun, so for our next trip we'll be rethinking the covering.
I cannot thank you enough, I love my domes! They're fantastic. Now to find the weekend time to build the 5/8!
