Fussy Cut Trio Ruler set by Eleanor Burns of Quilt in a Day. 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 1/2”, 4 1/2”, and 6 1/2”. Quarter inch lines are provided for seam allowances. Perfect places for Fussy Cuts are the center or four corners of your block, or Cornerstones.
