This project was the genesis for an instructable I posted earlier called Drawing Machine https://www.instructables.com/id/E0NF3EW9NQEWIJM3KK/
This project takes a more mellow approach and makes the post office make your drawings for you.
You will need:
-A shipping package
-A suitable sized piece of paper
-A "stylus" of your own making
-Money for postage
-An understanding friend
