Purschesed a shade cloth from shadecloths.com [actually got two as min order was $180] Since i got a spare i got one 30% and one 40%. Installed the 30% think i should have used the 40% as it's still hot in there. First time i've done this, used 3/8" rope through grommets to spread the tension, then installed eyebolts in attached shed. haven't secured the other ends yet was thinking bungees but afraid to snag cloth on the many sharp ends due to poor install. Appreciate any feedback, heres some pics.
