Picture hanging cord 🤷‍♀️2m (West Meads PO21)

I guess most sorts of cord would work 🤷‍♀️. I’ve got a big picture frame and picture of us for Father’s Day for the other half, sorted the fixings etc but don’t have any cord. With Wilko gone I’m not sure where to get it and feel like buying a whole spool online when I need like 2m is wasteful🤔…so I wondered if anyone on here had any cord suitable for hanging a pretty heavy a3 wood and glass picture frame above a fireplace? 😬 I can collect most days if you’re near Bognor/Aldwick. Thanks in advance 👍
