AIDA is not only an opera, Paul. With my 'Fabric Fairy' head on, I can tell you that AIDA is also the standard fabric used in the lower levels of cross-stitch. Whilst keen to promote all aspects of the industry in which I find myself employed, I very much doubt, however, that the huge cruise ship in Dover today will be filled to the gunwhales with enthusiastic cross stitchers!
On the other hand, if it is, perhaps I should hightail it down to the Cruise Terminal and set up shop for the day!
