I applied the Limited Collection by Marks and Spencer undercoat (similar here) to my nails first. I then applied a first coating of the varnish and once dried, and went over with a second layer to make everything stand out more. The candy cane polishes are just £4.90, which is great value for such a unique product. I finally finished off by applying the Sally Hansen Miracle Gel Top Coat which is a must have when I apply any nail varnish. It is a thick gel like consistency that is suppose to mimic shellac. It works really well and keeps nails from chipping, I had this on for 5 days and I took it off as I wanted to change to colour.
