Yes it's me again teetering on the brink of bad taste.
Sorry about your nerves Aunt Sally. But, today in Tesco's I saw a bag of 100 plastic balls for £3.87. I was, at the time, looking for tennis balls to put on the end of my canes to stop the bird netting poking through. So I bought them and cut little crosses in them, blew into them to re-inflate as they crumpled a little and stuck them on top of my canes. They look really funky and do the job a treat.
