Aria by Gudrun Erla creates the illusion of curves through structured geometric piecing. While the finished quilt appears complex and fluid, the construction is streamlined and far more approachable than it looks. The pattern is compatible with the Creative Grids Stripology Squared or Stripology XL ruler, allowing for efficient cutting and improved accuracy. Instructions for using regular rulers are also included. Aria adapts beautifully to both two-colour designs and bold multi-colour layouts, making it highly flexible for curated bundles or stash selections.
