I am ALMOST done with the new run, and I have 14 gauge hardware cloth left to put on. I cannot for the life of me roll it out flat!!! It has a continuous roundness to it, no matter what I do. Even if I cut off a piece, it is not flat. Is this the norm?? I am doing this myself, and it is hard to menuver. Is there some "trick" I don't know about? (Hubby is away so he can't help.) Thanks!!
