I have done this technique before with glitter sand. I think I posted a pictorial to Instagram though. For that one I used sand glitter. Here I used very fine holographic glitter.
This is a very simple technique. I would just say to work fast.
Base color is Morgan Taylor in Deja Blue
Fantasy Maker Confetti
Ulta clear coat.
Note: when stamping with clear polish,it is best to use non-fast dry clear.
Jumbo Cheeky Plate 8
feathered art brush
Stamp on to your nail,then quickly dip in the glitter.
Wait 5 minute before lightly brushing off access.
Out of focus to see how this glitter shines. The camera doesn't always pick up the holographic effects.
