1. Start by ensuring that there's no shine on the surface of your nail by using the 'smoothing' side of a nail buffer. (You can get a really good multi-sided nail buffer from Primark for about a £1). Easy.
2. Select a wrap from the sheet which most closely matches the size of your nail. There's a variety of different sizes and you can trim them if there isn't one suitable.
3. Place the wrap at one side of your nail, so that the edge lines up with the cuticle. It's much easier to start from one side of the nail and work across, rather than starting at the bottom of the nail and working up.
4. Apply heat to the wrap from your hairdryer (on a low setting). On the instructions it says for a few seconds, but I'd say do it for as long as you can bear. The wrap softens with the heat, and the softer it is, the easier it is to manipulate, so the more heat your apply the better. However, please don't take this to mean that your should burn yourself. That is not my intention. I don't want any hairdryer related injuries on my conscience. I just don't need that.
5. After applying heat, take the flat end of a wooden cuticle stick, and smooth the wrap onto the nail, going from one side to the other, ensuring there are no bumps and creases on the surface of the wrap. (if you do get a crease, apply more heat, lift the wrap off your nail and start over).
6. Rub the cuticle stick over the entire surface of the wrap, to ensure it is fully adhered to your nail. (you can apply more heat here if you want)
7. Trim most of excess wrap with nail scissors, leaving a couple of milimeters above your actual nail. File the remaining bit away, by filing your nails gently, in a downwards motion. This for me was the trickiest bit as you want to get the end of the wrap to line up smoothly with your actual nail. Just take your time with it and don't be too rough. I used a nail file from Boots that had different sizes of grit on it; use a really rough grit to remove most of the wrap, then a finer grit to neaten it all up at the end.
Voila, you're done! I just read back through those steps and realised it might be better to do a video tutorial to show exactly how to apply them. There could already be tutorials online, I've not looked, but if anyone would like to see one, let me know and I might just do it!
