Wanted: Jam jars and lids

I’m after empty jam jars and lids from lovely people in the Homerton/Hackney area.  I’m trying my hand at making some jams, and rather than buy them, I was wondering if I can be green and help people recycle their old jars 🙂 Not so much a swap, but happy to donate a jar of homemade jam to the kind jar donator (if it comes out well!) Thanks all, Rachel
