Stained glass pattern using page folds

Here's an example how to create a stained glass pattern using page folds. The original draft in the upper right section is easily tranferred (mirrored) into the bottom right section of the pattern.
Now you can fold the pattern on the vertical line and transfer the design to the left side of the pattern. Once done you now have a completed pattern that can be duplicated onto a working copy for templates. The original drawing is used for constructing the stained glass window.
