Alright these are some of my favorite nails to do. Beware because they do take a lot of patients and time. You will need....

1.diamonds it 'really matter which kind as long as they have a flat bottom. You can find some good ones at hobby lobby in the scrap book section. If you get the ones in lines on the paper with glue on the back it makes things a lot easier. They are usually around 2-3 dollars a pack
2. super glue they have some really good brush on glue at walmart in the nail section. Its around 4 dollars.
3. Gel top coat which you can buy from sallys and it usually runs about. Its around 6 dollars.

Start off one nail at a time. Make sure your nails are clean and don't have nail polish on them. There are two different ways to do this the first way is put super glue on a small spot and then add one diamond at a time going from bottom to top and then working your way to the other side of the nail one row at a time. If you bought the diamonds that are in strands on the paper you can pull them off and measure them to fit your nail one strand at a time. You will run into the problem of having extra space at the end of your nail or having the diamond hang over but either way its fine because you can file them down after the glue dries. Just make sure you are working from the bottom of the nail to the top and from one side to the other. After your done doing this to all your nails go over them with the gel coat. As I said before be patient cause it does take time, but it is definitely worth it. I promise you will get lots of compliments! Also the better the super glue the longer they stay on. Enjoy!!
