The harsh winter had made the previous cover very brittle and holes had appeared, therefore a new one was required. After searching the web I found the cheapest one through amazon, it had to be minky as my washing line is minky. After unzipping the new cover it fitted perfectly over the top of the closed rotary line, then from the bottom zipped up to the top, fitted in seconds with elastic at the bottom to stop it blowing off in high winds, previously having to tie the old one with string. I would strongly recommend this cover to anyone...brilliant.
