Don't put new shoes on the table, it brings bad luck. (Not sure if I'd put any shoes on the table).
Always have a supply of salt and oil in your house or you'll become poor (That's one of my Dad's).
Don't mock the afflicted, what goes around comes around.
Always keep some paper money sewn into the hem of your dress or your knickers so you don't have to stay with a date that isn't working out well.
The way to a man's heart is through his stomach.
If you see a magpie on it's own, salute it and say 'Good Morning Mr Magpie' or you'll have bad luck. (You may also be carried off in a white van).
Never wear second hand shoes, always walk your own path in life.
Position a mirror opposite your front door, it will keep burglars away. (Apparently they get a shock when they see themselves.)
Never wear green, it's unlucky. (I love green and wear it at any opportunity, much to my late mother's annoyance.)
Don't put all your eggs in one basket.
