To get a sharp, clean wing every time, you need some tape. Take household scotch tape and rip off a piece for each eye. Press it on your hand once, to remove most of the strong adhesive. Then, stick it at an upward angle near your lashline to direct the pen into the right design. Sketch away, and then take off the tape. The results will look like you used a stencil.
It's so simple, and yet, few know about the hack. With wings like these, you will be flying away to glam planet. Once you try this method, you never go back!
