This video made me think of this community. Fixing a camping chair and stool with Tyvek is pretty inventive, as well as sewing a tent with the material!
Did you use an off-brand tyvek? And tucktape? People make sails out of tyvek because not ripping is one of its things.
We’re definitely thinking of different materials. Or, perhaps something has changed in a decade+.
Regardless of where I’ve gone wrong, you’re right about Tyvek. Would be cool to have some cheap & easy to fabricate shaped tarps.
