Circe (SIR-see) is a simple but dynamic arrangement of half-rectangle triangles (HRTs) that creates a bold design spiraling across the quilt. The Two Color version is graphic and striking; the Multi Color version is a precut-friendly option that opens up a wide number of creative possibilities. If HRTs give you pause, never fear! Circe’s HRTs work with a standard Bloc Loc® ruler size for super easy trimming; also included is a special template for making your regular acrylic ruler into a custom HRT trimming tool with both right- and left-handed pieces.
