Unexpected spiral

For the Sunday drive of my Singer 66 treadle machine, I’m continuing to sew quilting scraps together. Sewing regularly with the antique machine keeps all the parts running smoothly. I’ve started in on log cabin patterns: starting with a short piece and adding on longer and longer strips. I was distracted by something during sewing (not unusual), and messed up my intended pattern. I soldiered on anyway, and at the end was a little surprised that I ended up with a spiral pattern with the cream and red fabrics. Huh. Going to save this one, and try for it intentionally next time.

I noticed as I posted that the colors of the fabric also coordinate with the sewing machine. Who even am I?
