footprint for 5m bell tent

[poppyboo]

Where can I get one from? It was a pain trying to wipe mud of the bottom of the tent when we were packing up last year and I want to avoid transfering mud from the bottom of the tent onto the canvas...

I bought a taupaulin sheet from B & Q for about a tenner and used that - just folded it roughly to size then tucked the edges under the tent once up. Job done
