Making a list of odd numbers from a list

I need to take odd numbers from a given list of integers to create another list. I have written an isOdd function, but couldn't make the rest work.

isOdd :: Integer -> Bool
isOdd n = rem (abs(n)) 2 ==1 

takeOdds :: [Int] -> [Int]
...

Suppose the list is 

x = [1,2,3,4,5,6]

and we can call the function odd using the code

filter odd x

and the result is 

[1,3,5]

If you want to use your own isOdd function, you can define it like

isOdd x = (mod x 2) /= 0

and the function isOdd can be called in a similar way like

filter isOdd x

The result is the same.
