Newest Mosaic Dress August 9, 2017 Birthday Dress for Amanda I made this mosaic dress form from sculpting wire, rigid wrap and styrofoam. The gold tone necklace at the waistband is one I purchased over 20 years ago. The blue stones/gems around the waistband and bottom border glow in the dark. I really had a difficult time deciding upon grout color. My perfection gene was surfacing so I just listened to my intuition.
