The pin-stripe style, aka the pencil cut, is a super-thin version of the landing strip. Just leave a thin line of short hair, starting above the clitoral hood and rising to the top edge of the natural pubic hair line.
Unless you have a very steady hand, it might be worth using a soft, bendy plastic ruler as a stencil. Any flexible straight edge will do, so long as it easily bends to the curve of your vulva.
First trim your pubes short all over, to a length of about 6 to 10mm. Then lay your stencil over the hair you want to leave behind, and shave along the edge. Flip it around to do the other side.
