Samples 2016: Week 6, Ripple/Fireworks

The pattern is "ripple", and the colour scheme "fireworks" - but my ripples look like firework patterns anyway! It started out as the concentric rings you get from dropping something in a still pool.

I used a flower stitcher attachment on my Bernina to make little circles of zigzag (straight stitch didn't show up enough). On black cotton backed with craft Vilene.
