Hello,
Below you have PUP = Public Utility Pattern - a template to facilitate making DCNotes or elements of DCNotes.
One way is to download the DCN_PUP.jpg file and print it out (horizontally) on a standard A4 or US letter piece of paper. Then you can draw in black inside the frame.
Have fun and let us know when you are happy with the results.
You can also work with it digitally, remember, ideally we want vector files (.svg, .ai)
Note that the DC logo is smaller on PUP, also, the right hand side of the frame is generally used for textual information (but those things can be adjusted later). Your drawings can, of course, be made larger and then reduced, still, PUP shows what the final result would look like.
