So you might have guess from the title of this post that I used a makeup sponge to do these nails! I was in the mood for lots of colour and so I used 4 colours: red, blue, green and purple for this. First to make the colour brighter I painted my nails white. Then directly onto a makeup sponge I dabbed my 4 colours closely together and applied this to my nails topping up the polish every second nail. And this is what it turned out like. I really like the way it turned out especially on the nails that got blended more, it kinda reminds me of tie-dye tops and stuff.
