I'm going to be covering a 1/3 scale plane and am wondering what people use as a straight-edge to get a nice clean cut on very long sweeping arcs? Once I thought about it I realized that my design patterns have always between straight edges that are connected with fairly small arcs. On those I could use something like a glass or even a cooking pot to give me a cutting guide that couldn't be cut in to with an X-acto.

Thanks for any information.
