For those who love hand made lace.
I don't know how this would work out for pulled thread, but I like it. I got the amoeba-looking parts by staring at a blank screen and drawing around the shapes that appeared on it. Somewhat like seeing pictures in the random dots on a popcorn ceiling, or the lines and splotches in marble. When the shapes appear to be real things, such as faces, it's called pareidolia. I don't know what you'd call seeing coherent, but random, shapes like this.
