My biggest bargain ever was probably a hexagon quilt I bought from a car boot fair for £1.50, back in 1988, as a student. I had to repair a lot of stitching and it wasn't quilted, just basted (in rough basting thread, so I removed those Stitches) but it has had a place in every home I've had, ever since.
Currently hanging over an arm of my long sofa.
Nowhere near as many hexagons as that one, mind!
