Gradient nails are fun to do using the MoYou London Sponge Kit.
The sponge kit comes with a holder and six re-usable (non-latex) rectangular sponges. Suitable for beginners to advanced skill levels. Use Liquid Nail Tape around your cuticles for easy clean up. With a little practice, you will be blending and mixing up colour combinations in no time and your nails will look amazing.
Starting with a white base will give your gradient extra depth.
Apply at least two nail polish colours on the sponge. Then lightly dab the sponge on to your nail. Repeat till you happy with coverage.
For an even blend in between gradient colours, overlap their application slightly. After a few coats, this method creates a smoother blend!
