I did this a few years ago on Instagram and it was really fun. I posted a bunch of Copperplate and Spencerian capitals behind a “door” image each day until Christmas. Instead of posting a bunch of pictures, I am going to post one with all the variants on it, each day until Christmas. Feel free to comment or add some variants.
These are capitals I am playing around with in ProCreate on the ipad and will some day translate to pen and ink if possible. I love ProCreate for the free flowing pen tool and ability to redo as many times as I need without wasting paper or ink. It doesn’t always translate to pen and ink later because of the pressure and directions I go, but still a useful exercise.

Hope it inspires you to play and create your own!
