I think i'm going slightly OTT with the scavenging but plucked up courage and asked at the local carpet shop and have acquired as many cardboard and plastic tubes as i like (the wide ones which carpets come rolled round) and as much carpet ends as i need for paths etc. Has anyone got any ingenious use for them, does anyone use them already, can you fill them with compost and grow veg in them on the patio? I would be interested to here from anyone.
