Both.
If I wash clothes first, I will take it out for washing lines to dry it as I prefer outside because it is more fresh and smell crispy....
If my DH or my daughters wash theirs, they will using dryer as well and less time to ironing.
For my bras, I don't like to use it in dryer because it will cause bad and mishaped, I am fussy as it is.
My washing line is hide from my backyard as I understand it can be eyesore if it is in the middle of backyard for everyone to see!! I shift my washing lines because my golden receiver dog used to pull sheets and towels out of washing lines, as I was told it is because he miss me alot and miss my smell from it!!
It is difficult to dry sheets in the dryer isn't it? it will turn into a ball!!!!! For me I rather to use it on the washing line.
