I created a sideways gradient with two of my gelly polishes. I picked Papaya and Grapefruit because I thought they'd blend well together. Turns out, they blended a little too well! You can hardly see the gradient at all because the colours are so alike! My nails do look nice, I love both the colours and the shade the blend creates, it's just annoying that you can hardly tell. I might try doodling over the top of this with my Barry M pens!
