If you look at the fabrics in person with 3-D glasses, they really do look dimensional. And without the glasses, they just look like nice fabric, nothing weird or blurry or shadowed about them.
Our Hoffman rep came around about a month ago to show them to us, and of course she had her glasses with her!
And I did try looking at other fabrics with the glasses on, and they didn't look terribly different. So it must have something to do with the colors that they chose and how they arranged them on the fabric.
