It was suggested to me that I should try crumb quilts and after a look on the internet, found several sites of interest and started sewing. So far this is what I have made - with a bit of a border it could well be a cot quilt. I shall take it with me on my next fabric buying trip and find something to coordinate. As, believe it or not, I have nothing in my stash that is suitable.
And here is a close up of the tiny pieces, some were only an inch square.
