Hello there-
Well, to make it short, you find your picture, transfer it onto some batting. Then you chop up your fabric using a rotary cutter NOT scissors. Then you sprinkle the tiny pieces onto the batting which is laying on top of your backing. You have to work flat on a flat surface. I encourage students to use a design board (think cardboard or foam core board). Once the design covers the batting to your satisfaction, you cover the whole thing with bridal tulle (fine netting) and you quilt it to death with your machine.
Got it?
