Rubbing alcohol and scrapbook paper; it transfers the designs onto your nails! I've done this with newspaper, but I never thought to do it with scrap booking paper! And it also works with vodka, if you don't have rubbing alcohol.
I never thought of this but this would work and the glitter wouldn't chip easily like it does as a top coat. A coat of glitter in between two layers of color = marble effect - never thought of this, must try!
Super Easy Nail Polish Remover Jar DIY: take a cheap sponge and cut it so that it fits snug in a small jar with a lid. Fill about with nail polish remover and twist fingers one at a time in the center of the sponge. This is an excellent idea! :D
