Optimistic Post of the Day

I’m looking to make a simple fabric canopy to provide a bit of sun shading for the kids. I was thinking of spanning it off the back wall of a stone shed to two deer fence poles so I’m looking for a netting type fabric which won’t act as a sail and catapult the shed wall into South Yorkshire.

Does anyone know of a relatively UV stable/weather resistant material which will give say 50% screening (anything would be better than nothing but even though the kids would love it Mrs Richie_B isn’t going to go for camo netting).

Thanks
