After 15ish years we decided to retire our old dome tent, so I have several good quality parts to work with. There will be three arches with approximately 50 inches between them.
So after getting all the measurements down the wind took my note pad and threw it in the water. Grrr. This project might be cursed.
I came home and recopied all my measurements from the soaking wet paper on to a new piece of paper.
This might not work....... Then again it might...
This is a pretty rough start. I think I'm going to make a proto-type with some old fabric creating a rough pattern to work from before building a true final project.
