What about something like this as a possible idea of Rob's that I like too?

or the thicker 24mm, although not on offer here!

The weight of this stuff may even be enough to negate the need for pinning it down!
We could even look to get it in colours if possible.. for example (you need to click on the leisure marine pic and then scroll down to the Polysteel - 24mm on the right hand side half way down. The yellow stuff at £1.50 a metre looks a bargain to me).

What you think?
