I know. My mandala doesn't look very impressive. But. It's holographic! Twist it in the light just right and a whole different mandala appears! My great-nieces (5 & 7) were SO impressed!
I'm not big on mandalas. I love seeing what others do, but have never had much interest in drawing them myself. So for this prompt I grabbed the Quasi-stencils I won from Artist Cellar a while ago, and used one for the dotted background, and two for the blue mandala.
How did I get the holograph? I used Daler-Rowney's Graduate Metallic acrylic in pearl-white with my last stencil. All their metallics are very transparent, and the pearl white is almost invisible. Until you hold it so the light can catch the sheen. It's a cheap thrill, but it's fun, lol!
