Fabric for making outdoor cushions

[SpaceTrain]

Can anyone recommend me somewhere online to look at fabric options for making outdoor cushions? I want the fabric to be weather-resistant and fairly bright patterns - if possible along the lines of the cushions in this pic

Any ideas? Thanks!

Cath Kidson do some material that is like thick table cloth/waterproof materal that might be useful. I know it's available in Kidson Stores but not sure where else.

Thanks pm. I will take a look to see if there is anything online at Kidson.
