Okay so you're going to get out the three primary colours on a paper then for later your going to mix them
Put a quick white basecoat over your nails. Wait to dry
So with a small paint brush(not the one pictured)pick a colour and do a small swirl on your nail, mix with other colours to get an almost tie dye effect.
So the nails would look something like this.
the best thing about working with paint is that you can just wipe it off with water or the tip of your finger.
Once dry glaze over a clear coat and your DONE!
