When your laying out parts on your cutting diagram, it’s important to remember that the wood grain runs lengthwise on a plywood sheet. It just needs to help you organize the parts effectively, and to serve as reference when you cut. Your cutting diagram doesn’t have to be perfect, or even pretty. That way you can erase and move parts around as needed until you create an effective parts layout. Draw the 4’x8′ sheet border in pen, and then lay out your parts using pencil, as shown below. And you can draw a full-size 4×8 sheet of plywood on standard printer paper. Paper with 1/4″ squares works great, as you can make 1 inch equal to 1 foot (which makes each 1/4″ square equal to 3″). Just go online and search for “printable graph paper.” You’ll find lots of free options. That used to mean making a trip to an office-supply store, but these days graph paper is as close as your computer. Rather than start with a blank page, draw your cutting diagram on graph paper. Whether you’re reworking a cutting diagram from an existing plan or you’re designing your own project, knowing how to make your own cutting diagrams gives you options.
One of the best ways to get better at working with plywood is to learn to create your own cutting diagrams.
