I think this was knitted as a sample or experiment. You could use it as-is, or you could unravel it and use the yarn for something else. It’s a relatively bulky variegated yarn with an interesting construction — a thin outer yarn wrapped around a loosely-spun interior. I don’t know the fibre content.
Pick up between 9am and 5pm on a Tuesday, Wednesday, Friday, or Saturday. Location is 3 minutes' walk from West Croydon Station. Priority given to people who are nearby, and who tell me in their first message exactly when (date and time) they want to come.
