Cat's quilt from "The Amelia Challenge Quilt"

Here is the finished quilt top of Cat's quilt that she made in The Amelia Challenge Quilt. Those of you who have read the book will know she was inspired by the tessellated tile floor in the arts building at Melbourne University. This top has been pieced using the English paper-piecing method in order to maintain full fabric pieces for all the elements i.e. I didn't want any joins in pale grey fabric. The quilt is not particularly large at 43" square and is intended as a wall hanging. Every piece is directional, except for the border.
