Start out with a base coat and paint all your nails white. Next take a makeup sponge and dip it into blue polish creating a blue circle in the middle of your nail. Then use a green polish to create a ring around the blue polish. Then use a yellow polish to create another ring around the green. Use a red polish for the final ring. Now use a white stripier to create fine white lines coming out from the blue. Now you have some groovy tie-dye nails.
