Carpet (Malvern Link WR14)

Has anybody got the cut off length of carpet from when they had new fitted, maybe lurking in the loft. We moved recently and are doing a lot of updating to the property and with winter looming could do with a carpet runner for 2 hallways to take the cold off, we need anything between 60cm to 100cm an about 3 to 4 metres in length, any colours, we would be very grateful, thank you for reading
