how to do a fishtail braid pattern on your nails. They are really pretty easy but look so effective. So, start by painting your nails with a base colour, using the lightest colour you are going to use for your fishtail manicure. Paint a diagonal line in one direction from the base of your nail using your second colour. Then, a diagonal line opposite this using your third colour. Take your first colour again, and paint another diagonal line across your nail, slightly lower down from where you put your first line on the same side (so, basically, leave a small gap of colour there). Repeat this again with the next colour on the other side. Don’t worry too much about how it looks at the moment, as it will start to take shape pretty soon! Keep repeating the same process, one line each side, rotating the three polishes that you are using. Try and keep the widths similar sizes so that it will remain symmetrical all the way down. As you can see, you don’t need to paint completely down your nail, just enough so that the strip of polish crosses over to the other side. Keep going until you’ve covered your nails, and once they are dry, apply a top coat.
