Supplies needed: Black origami paper (Yasutomo #4601) White origami paper (Yasutomo #4608) Purple origami paper(Yasutomo #4609) acrylic interference paints in violet, gold and blue sea wool sponge rubber stamps in bold designs gold pigmented stamp pad crystal clear acrylic spray (optional)

Instructions:

First lay out newspaper to protect your work surface. Place origami paper on the surface colored side up. Dampen your sea wool sponge and squeeze out excess water. Put some gold interference acrylic in a shallow tray and mix with just a drop of water. Take your sponge and pick up as much interference color as it will hold, then dab the color  lightly onto the origami paper alternating directions with the sponge as you go. One load of the sponge will cover quite a bit of origami paper. Repeat the entire process with the violet and blue interference colors. This process is quite stunning on the black origami but is also beautiful on the white. 

Tip:
Stamp random designs on the paper with pigmented inks, then spray lightly with clear acrylic spray for a durable unique paper that you can use for any origami or paper project.
