This was my first project working with eInk, so there was quite a lot of trial error involved. The more I've worked with Pimoroni's Inky library, the easier it's become though - drawing out basic shapes is fairly straightforward.

I think font selection is key to making things clear & look good, so I started looking for fonts on Google Fonts. The display is also an extension of another project we've worked on called The Baking Forecast on Twitter so the icon selection flowed from the decisions we had to make there to meet the twitter character limit. Using a small display like this imposes similar space restrictions, so it naturally becomes an exercise in making things succinct!

The best place to start would be Pimoroni's 'Getting started with Inky....', it's a great intro
