I’m working on this weird stylised peacock inspired quilt. As it came together it tweaked some aurora borealis vibes.
I’m planning on quilting with a loose horizontal wave, but I don’t know what colour to use for the top quilting.
The back is a green and grey plaid.
I don’t think I can offer a better suggestion than purple and / or shiny - I just wanted to say it looks like it’s going to be amazing, and I’m looking forward to seeing the finished quilt!
I’d say it depends how much you want the quilting to stand out. Putting purple on those light colours will make it very prominent as will any colour except black on the black. If it was me, I’d want the coloured areas to pop so I’d do black on the black and an off white or ivory on the colours.
If you want to underscore the aurora borealis vibe could you lean toward a light colored iridescent? Or, and I know this is wacky and not everyone’s cup of tea, but, I was given a cool quilted tree skirt that had glow in the dark stitching. It was fun!
