It can be difficult to position a hole punch without a mark. The dots on some of the shapes are where I most often would be making holes. You may want them in different places. Make sure to keep an original template with your changes on it to copy for later use.
The template is divided into 2"x6" sections because my sticker maker accommodates a 2" width of paper. The entire sheet can be glued to a 6"x6" piece of metal. The pieces can then be cut out using your preferred method of cutting metal.
