This looks very spangly. It was part of an exhibition from various artists in our town. There were various objects shown is different places. This was on a path from one of our bridges and was patchwork similar.
My actual memory of a spangle is a sweet that was sold when I was a kid. They were known as spangles and were square boiled sweets in various colours, not very good for the teeth, but we kids knew nothing about that, we just enjoyed crunching them.RDP Wednesday: Spangle
