After the wonderful help here, I found a nice, close-ish LQS and selected my fabric today. I bought 2/3rds of the full amount so I could make slightly more than half the units as suggested. One fabric per color and purple instead of gray. They are somewhat brighter that Bonnie’s, but the values are right (I think) and I love batik fabrics! Hopefully it comes out nicely. The gals at the LQS were impressed with my use of my phone to photo and convert to monochrome to make sure I got the right fabric and my eye for values improved! 😁
