Carpet underlay leftovers - 6 sqm (Abingdon-on-Thames OX14)

Hi,
Looking for some carpet underlay leftovers of any kind. Only need 6 square meters so feels like a waste to buy a new roll (>15m) and throw two thirds away. If you have some underlay that is enough for 6sqm lying around in the attic and gathering dust I would be happy to liberate it :)

Thank you!
