For Sexual Assault Awareness today, everyone is wearing teal and/or jeans at my school. So... I did denim nails. This was my first ever try at them, so I am fairly happy with how they turned out! ^.^
For this look, I only used one nail polish, and that was as my base color: Sally Hansen's Thinking of Blue.
I sponged, linearly, with dark and light blue acrylic paint to get the semi-cross stitch jean look. I did the dark blue (Apple Barrel's Bright Blue) horizontally, then light blue (Folk Art's Deep Ocean Blue) vertically. I think a more porous sponge would have helped achieve this effect, but I just used a soft makeup sponge.
For the stitching, I mixed yellow paint (Apple Barrel's Bright Yellow) with just a teeny tiny bit of red (Apple Barrel's Bright Red), and an even teenier bit of black (Apple Barrel's Black).
I then finished with, of course, a matte topcoat. e.l.f.'s Matte Finisher, to be exact, to both protect the acrylic paint, and because jeans are not shiny, silly!
