The flag does not have reflection symmetry due to the slight pinwheeling of the St Patrick's and St Andrew's crosses, technically the "counterchange of saltires". Thus, there is a correct side up. The original specification of the Union Flag in the Royal Proclamation of 1 January 1801 did not contain a drawn pattern or express which way the saltires should lie; they were simply "counterchanged" and the red saltire fimbriated. Nevertheless, a convention was soon established which accords most closely with the description. The flag was deliberately designed with the Irish saltire slightly depressed at the hoist end to reflect the earlier union with Scotland, giving as it were seniority to the Saint Andrew's cross.
