How can you make your nails narrow?

You'll need nail clippers, and/or toenail clippers, and a nail file. If you want round ends on your nails, use the normal nail clippers and cut roughly the shape your want, then file them in ONE DIRECTION ONLY to perfect the shape. Filing back and forwards with make your nails split, which hurts and looks bad. For square tips, use toenail clippers or nail scissors and then just file straight along the top, again, not back and forward or you'll split your nails, and round off the sharp corners slightly so they don't catch on things like your best jumper or tights.
