Ill weeds grow apace.
Keep a thing for seven years, and you will find a use for it.
Kill two birds with one stone.
Lazy folk take the most pains.
Let sleeping dogs lie.
Let them laugh that win.
Make hay while the sun shines.
Many a true word is spoken in jest.
Many hands make light work.
Marry in haste, repent at leisure.
Never look a gift horse in the mouth.
Necessity is the mother of invention.
Old birds are not to be caught with chaff.
Old friends and old wine are best.
One swallow makes not a spring, nor one woodcock a winter.
People who live in glass houses should never throw stones.
Possession is nine points of the law.
Procrastination is the thief of time.
Short reckonings make long friends.
Safe bind, safe find.
Strike while the iron is hot.
Take care of the pennies and the dollars will take care of themselves.
The more the merrier, the fewer the better cheer.
The darkest hour is just before the daylight.
The cobbler's wife is the worst shod.
There's many a slip 'twixt the cup and the lip.
There's a silver lining to every cloud.
Those who play with edge tools must expect to be cut.
Time and tide wait for no man.
Too many cooks spoil the broth.
