A fussy cut is a selected image, such as a flower, centered on your patch. It's so easy to do with the Fussy Cut Ruler Trio. Select an image from your fabric to center in your block. Cut around the ruler with a rotary cutter. Move ruler to next fussy cut, and repeat. Your remaining fabric looks like Swiss cheese after fussy cutting. Perfect places for fussy cuts are the center or four corners of your block, or Cornerstones. Trio includes three sizes of rulers: 3-1/2", 4-1/2", and 6-1/2".
