ask and ye shall find, phoned around a few places and on the net, quoted £7.40 per mtre for fibre glass tube, metal tubing also quite expensive. Would have prodably cost around £20-£30 for tubing, then I would have had to make connectors and corners. Taking Ians advice, looked ar Argos Gazebo £11-99, went and got one, got everything I need for two frames, corners etc, and will still be able to use it as a Gazebo. Cheers for the help lads. Only way I could have done it cheaper is if I was still at work.
