Applique a little lady bug or something on the spot. My daughter made a king sized Sun bonnet sue for a lady and somehow some black grease or something got on a little spot and she tried and tried to get that out and when she did it left a little area and so she appliqued a little bluebird on the area, and to make it look like it was supposed to be there, she appliqued several other blue birds randomly so it looked like they were supposed to be there.
