My wife and I are Lab technicians at our local Community College District. She came to me with a problem that I didn't know that I even had...how to consistently and reliably mark quadrants on the media plates that we hand out to students. She asked if there was a way that I could make a rigid stencil for her to be able to draw these lines perfect every time because the laminated stencil that she cut on her Cricut just wasn't cutting it (sorry but not sorry for the pun).
