No special technique for this card. I stamped with metallic acrylic paint, applied with a dry brush, on black gloss card. Be sure to clean your stamp right away if you don't want the dry paint stuck to your stamp. Stamp is Beautiful Dreamer by Curious By Design. Blue background piece is also metallic acrylic paint and embossed with CB Folder. I also made the pink version of the same card below. Hope you like!
Until next time. Be well!
