Scrappy layer cake pinwheel

my quilt group make quilts for a charity called Siblings Together who provide care for children in care seperated from their siblings. I decided to cut layer cake size squares from my stash to make a quilt suitable for an older child. I love watching Jenny's Utube videos and decided to do the pinwheel quilt. I have quilted the dark squares so far and intend to quilt the rest with a meander pattern.
