colored pencil drawing

I'm continuing with several drawings like this, growing geometric networks that look like cells or bubbles packing together. I'm starting them all similarly by laying down a triangular array and then building upon that grid in various ways using only straight lines without a ruler. I start at a single point on the paper and grow shapes to the edges of the paper, and I stop when I can't draw any more shapes without going off the edge of the paper. I'm thinking of the paper as an environment with a carrying capacity for life, and my little blobs are life. The edges of the paper are real boundaries. The paper is not just a window into some other world. It is the world. I think of it as a flatland ecosystem, and my drawn cells are some sort of dimension-challenged beginnings for life.
