I have found some existing designs of calendars to influence my layout. I have come across some letter pressed calendars, which I love. Aesthetically they are great, unfortunately I do not have the time or facilities to create the same or similar effect. They best way I can think of is to make copper plates to ink up and emboss. To create 13 of these would take up too much time, so I think I'm going to stick to screen printing them, which will also make it easier when selected the appropriate recycled stock.
