Here are another set rulers that you might like too. Just in case you haven't seen them. I use these for curves, scallops ore even mark a quilting line for quilting.

PS: Another tip for those using paper templates. Staple your layers of paper together (away from cut line) so they won't shift when you cut out the design. The excess will be stapled and then you unfold the layers.
