There are tonnes of Christmas nail foils/wraps on eBay, and I recently bought 3 different sets for something silly like £4.50. This was the first time I've used nail wraps but found it pretty easy. My right hand was weirdly better than my left (I'm right handed) and I found not using so much heat worked better. Since these pictures, I have cleaned up the edges with a file a bit more.
I have 2 more designs coming up later in the month too. They come in 8 different sizes, so there should be a size to fit all.
