Like it says. Normally set up a flying wedge. 3m by 3m does for me.but what size is a good idea for 2?
A 3x3 tarp can be pitched like a tent as per this video - imho, it's deceptively roomy and could easily fit two. I've only tried it solo in the garden https://youtu.be/MLlpSs9Dj3g?feature=sharedAs quixoticgeek says, shirley 3x3 as a standard ridge is big enough?
