thanks richard,
yeah, i wouldn't be worried if it were posters or maps (i carried a tube of rolled vintage propaganda posters around for months after buying them in viet nam - with hindsight, yeah, probably could have mailed them home!) but i was just concerned about thicker paper, as you say 'taking a set', especially as they would be in transit for a while, uk to aus.
i guess, if the order happens, i will just try and use the widest tube possible, protect them well, okay the rolling with the customer, and cross my fingers..
e.
