I'm using the Marti Michelle kaleidoscope rulers. You can make up to a 16" block with a 2" kaleidoscope center. I'm using a 4" center to utilize the best out of this fabric. Background black and secondary fabric a baby blue batik. My daughter likes blues and she has a thing about fake spiders, I think to drive me bonkers, age 40, go figure.
Should be beautiful without being a real spider web, eegads...
