When I was young one of my favorite things to draw and color was something similar to this. It's a crazy quilt style of movement, harmony and color. I began in the center of a page and let the pencil flow over the page intersecting, overlapping line and loops with one easy flow; then filled in the holes however I enjoyed doing so. Anyone else do that?
Modern quilt of colorful squares on a gray background with circles quilted over. Dynamic and subtle. The Flickr page includes a link to Cherry House Quilts blog which created the pattern, free tutorials with great pictures, and quilt-a-long.
