Below is an example of how to use lace stickers. The stickers are easy to paste and if you use a top coat to go over them, it can last 3-4 days, or even a week! (depending on how much washing and cooking you do too)

Pick up the lace sticker using a tweezer and cut according to the desired length.

Decide where and how you want to stick the sticker onto your nail and press the sticker down.

Using a nail file, file the excess sticker away. It will ensure that the end of the sticker fits the shape of your nails nicely. Try not to use scissors.
Use a good top coat to go over your nail stickers so that they will last longer.
