Squareathon 2021 from @melissadoty.art
Every September, Melissa Doty (@melissadoty.art), does a Squareathon Challenge. The only requirement is that all creations are square. She also provides some prompts that can help guide you. Here is my batch for this year. I used it as an opportunity to practice a technique from Painting Imaginary Flowers by Sandrine Pelissier.
