When we were recently in Sydney we were staying with my brother and his wife. My sister-in-law brought an item out of her wardrobe to show me. I was amazed that she had kept this item for so long. It must be at least forty years old!
A very simple crocheted poncho. I have no idea where I got the pattern but it looks like it is a granny square without the centre. Great that she kept it for so long.

Not as old as my lovely 21 st Birthday Jumper ,now 51 years old and still in good shape!
Hi Kate,
A bit slow in replying to comments! I had no idea you still had that jumper. Surely the moths would have had a go by now?
