I'll second Joff's comments, but add.............
I have used various types of tarps shadecloth etc over the years. Most of the time they work in one way or another.
Then life went pear shaped!!!
Along came little tin lids and threw a spanner into the works.
No matter how hard you try they trash everything they come into contact with.
Cleaning pureed pear etc out of camping gear fouled with regurgitated milk is ever so pleasant.
In a fit of crazed raged (It does happen if you spend enough time with the inlaws!) I decided that I should give the C-gear a go.
Wife commented on how expensive a piece of shade cloth it was. "yes I realise it's double sided- but it would still be cheaper to buy 2 and join together"
Yeah yeah, with what? when? etc etc.
its just easier with kids to go out and buy the product.
I'll tinker when I retire!!!!
Much to my dismay, the bloomin stuff works.
I have no idea how or why, it just does.
Of course as with anything that works fine, I decided to try and improve it.
As soon as I find somewhere on the matt I can put a screwdriver or saw, i'll get cracking, But for now it works so the boss, the kids and I are happy.
