When I hang my clothes on the line, I hang anything that might require ironing on a coat hanger and hang it over the line! Saves line space if that's limited, and the vast majority of the wrinkles just drop out, especially if there is a breeze.
Jut pop a peg over the hook to secure in place and you can fit lots of things on a small line. Multipeg sox to the bottom of the hanger to save even more space. Many things dont need ironing at all, which is alright by me!
