Summarize the following:
Ordinary, single-sided Scotch tape is the easiest to use on nails. It can be completely clear or a little clouded, depending on what you like. Scotch tape is a transparent tape, called Sellotape or sticky tape in some areas. Tear off a strip of tape about two times longer than your whole fingernail. Put the tape on your finger so it covers the entire nail and extends past it, so the whole nail looks glossy. Press the sides of the tape down firmly, so the tape bends like a regular long nail would. If the tape is too wide, have an adult trim the tape with a pair of scissors. Brush the sticky underside of the tape with nail polish. This will make the nails last longer and stop them sticking to things but make sure not to touch anything while you wait for the polish to dry. If you have a nail buffer, use sides 3 or 4 to rub the bottom of the nail gently. Do this over the lower edge of the tape, and it will wear the tape down, making the line less visible.
Pick a clear, shiny tape. Put a piece of tape over your nail. Cover the underside of the tape in nail polish. Buff the nail at the tape end (optional).
