I love old sheets. Old sheets are a lot like old friends.
Old sheets are comfortable, familiar. They're worn in and softened in just the right places. They even smell right. Not always good, but never strange.
They have a history - especially when they're yours. Sometimes they have marks and scars as a testament to that history. Sometimes they'll be worn so thin that you could break them like that with a twist of your pinky finger. Sometimes they're still going strong, years and years later.
So I suppose it's not surprising that I love to work with old sheets, refashioning them for new uses. They make wonderful house or pyjama pants - soft and light, and often 100% cotton. They're great for cushion and pillow covers - especially when they're worn thin in the middle, you can piece the edges of different sheets together. Being a simple woven fabric they're usually wonderfully easy to work with, already stretched as much as they will, not overly prone to creasing. And, when there's nothing else for it, they make marvellous cleaning cloths, soft and light, easy to wash and re-use again.
