Yes Tom I want to replace this bluey tarp and a friend has been searching round for Khaki canvas for his WOT (Everyone seems to have US olive canvas)
He's sent me a sample from a firm in Brum :- 'Classic Khaki 18 oz 6' wide £20 metre'
Ouch! Works out at about 18mts = £360 +post and probably VAT too! Getting on for £450 before any sewing!!!!
It's why I've deen waiting for someones old dead tilt
