Curtain track - short or cuttable (Tilekiln TN38)

I need a short length of curtain track with fixings to hang a single curtain over the doorway to our living room to keep it warm and to soundproof it a bit. There is no door and it’s a narrow doorway - doorframe measures 86cm but I could fix to wall above. I think curtain track is a better bet than a curtain pole as it can hang closer to the opening. Thinking someone might have saved a leftover bit of track!!

I can collect, Julia
