It should be noted that the red saltire that "graces" the post-1801 UK flag is NOT the legitimate cross of St. Patrick. It is an entirely English invention that never existed until the 1780s, when it was inserted as part of the badge of the English-founded "Order of St. Patrick". There was quite a furor in Ireland at the time against what was called "The Bloody Cross of Scotland" being imposed on Ireland.
St. Patrick's cross is a Cross Pattee.
