Pieced by Barbara C. Barbara marked the shamrocks in each center block planning to hand quilt but decided she wanted it sooner. I followed her markings with the shamrocks and found a stencil that created a chain effect in the alternate blocks. Thread: Signature 100% cotton (Daisy) Batting: Hobbs 80/20 Pattern: Stencils marked with hidden glow chalk and "read" with the black light.
