 Knights could encircle their arms with a depiction of the circlet ( a blue circle bearing the motto ) and the collar ; the former is shown either outside or on top of the latter . The badge is depicted suspended from the collar . They were also entitled to receive heraldic supporters . This high privilege was , and is , only shared by members of the Royal Family , peers , Knights and Ladies of the Garter , Knights and Ladies of the Thistle , and Knights and Dames Grand Cross of the junior orders . ( Of course , Knights of St Patrick , normally all being members of the British Royal Family or peers , were mostly entitled to supporters in any event . )
