I'm going to share here what went into the design choices. I will cover the construction details that are relevant to the nature of the design, but not attempt to cover basic piecing and quilting techniques.
Step 1: Source Pattern, Two-color Inspiration
Unikatissma has a Random Squares Pattern Generator that looks fun. I also find Cellular Automata patterns a good source of inspiration for two color designs, and my favorite tool for exploring them is Mirek's Java Cellebration . My next quilt is planned based on a "Life 012345678/1" rule automata.
