Optical Illusion Quilts

This year the quilt show had so much beauty, I divided it into smaller groupings to appreciate.  These are not the groups that they have designated, but my choices.  I found it quite interesting that there were a number of optical illusion quilts.  These are not new, they have been around quite a while, not all I am sharing are really optical illusions and I did not include all from the show.  One very popular quilt showed 3 different faces depending on where you were standing.  One direction was Jackie O., then Oprah, then Mother Teresa. I am sure this quilt will be at many shows.
