As in the title, just wondered if anyone knows of anywhere selling large sheets of cotton tarpaulin (in and around 12x10ft). Read some outdated pages on the net where people were talking about getting larger rolls from army surplus shops/warehouses, but all of the pages are expired or don't seem to sell the stuff any more. Cheapest I can find at the minute is around £60 per tarpaulin!
Surely someone knows of a cheaper source!!
