Fabric for cushions

[tillyfernackerpants]

I want to make a couple of large floor cushions but its the first time I've tried anything like this.

What's the best type of material to use for cushions? And a good place to buy it online?

Any thing really thick, old curtain fabric or upholstery fabric would do also corderoy. Floor cusions take a bit of beating so make them strong. Look on ebay there is loads of good stuff.
