A fussy cut is a selected image, such as a flower, centered on your patch. With a Fussy Cut Ruler, you can cut the identical image repeatedly with ease. The Fussy Cut Trio is a set of three laser precise heavy guage plastic rulers in these sizes: 3 12, 4 12, and 6 12. Quarter inch lines are provided for seam allowances. Perfect places for Fussy Cuts are the center or four corners of your block, or Cornerstones.
