Wrapping up for winter??

Two Wests and Elliot are good for this kind of accessory. Also stand plants (ones that are on the floor) on polystyrene sheets (or recycle those pot holder trays) as this keeps the cold from going upwards from the floor. As for botrytis, I think ventilation on reasonable days is the answer. Lets hope the winter is not too cold!

they sell it at B&Q barbara , i saw it the other day while i was there, might be a bit cheaper than GC or nurserys

Put a piece of fleece across the ridge of your greenhouse when you bubblewrap the rest. B& Q as mentioned is one of the best places to buy both.

Bubblewrap would probably be cheaper at Staples or other stationery suppliers.
If hubby's up for a challenge have a look at:

By golly, Wagger - that would be a project and a half! He's too busy playing with his cars, I'm afraid....

Thanks for the help, all. :-))

I was hoping he'd trial it for us, Spritz. LOL.

LOL. No chance!
