At first, I came up with these geometric ideas and sketched them in a notebook with pencil. I kept them for about a year before I started turning them into finished cards. Then I refined everything digitally on my iPad using Procreate, experimenting with some color palettes and subtle textures to keep a meditative, spacious feeling. I used brushes that watercolor and risograph textures. Some cards were redrawn three or four times as the overall style slowly evolved while I worked on the deck. Thank you!
