I don't have a clothes horse, had two but gave them away. I now have a plastic copy of an outside dryer, that when folded down looks like a mobile phone aerial ! It has 3 fold up sets of arms, one with holes and pegs, and the others just hang things on. I can get a whole wash on it, leave it by an open window and it dries the washing in no time.
I bought it in self defence as it's almost impossible to get to use the communal lines.
Friends who have wanted one have been dissapointed as they seem to have disappeared from sale.
