First, apply some base coat to your nails. If you don't have any base coat, go ahead and use top coat.

Next, coat your nails with your most watermelon-y shade of pinkish-red nailpolish! I used the shade "Jelly" by Revlon.

Now, take some lime green nailpolish and begin to create french tips. (this is always the part where I wish I'm ambidextrous, so don't worry if u screw up the first time:) I used "Wild Thing" by Pure Ice.

Now, start making some watermelon seeds with your black nail polish. If you have a dotting tool, you'll probably want to use that. I don't, so I used a straightened out bobby pin instead... it works just fine :)

Once your beautiful creation is done, apply some top coat... and you're done!!! Please enjoy and add your versions, and if you have any questions please ask.
BYEEEEE!!!!!!! <3 :D :) =D
