Summarize the following:
Take hold of the loose edge of the backing and peel it off in one smooth motion. Try not to let your fingers make contact with the adhesive itself, or it could lose some of its stickiness.  Your local sporting goods store may carry eye black stickers in the baseball or football section. If not, look for them online. A package of eye black stickers typically only costs $4-5, and often includes around 12 pairs of stickers. Hold the sticker over the flat part of your upper cheek just beneath your lower eyelid. Try to line it up with the middle of your pupil. Essentially, you want the sticker to sit between your lower eyelid, the point of your cheekbone, and the nearest nostril.  Some eye black stickers are curved slightly to fit along the contour of the player’s eye. If the stickers you’re using are curved, arrange them so that the curve is pointed upwards like a smile. Take your time to double-check that each sticker is positioned correctly before you smooth it down. Once you’ve got your first sticker situated just right, touch it to your skin and apply light pressure for a few seconds. Then, smooth the sticker from end to end with the pad of your finger to make sure it’s secure. There’s no need to bear down too hard—just be sure that every part of the adhesive back is making contact with your skin. Remember to align the sticker with the center of your pupil about 1 inch (2.5 cm) under your eye. Press the sticker to your face and run your finger over it to smooth it down. Both sides of your face should be congruent. Resist the urge to mess with your eye black stickers once you’ve got them where you want them. If they’re not, carefully loosen them and adjust their placement as needed. Just avoid removing them too many times, or the adhesive will begin to wear off. One major advantage of eye black stickers is that they’re much easier to remove than the stick. Just grab the edge of each sticker, pull them free, and toss them in the trash. Don’t attempt to use the same stickers more than once. There’s a good chance that they could come unstuck during a crucial part of the game.
Remove the backing from the adhesive sticker. Center the sticker about 1 inch (2.5 cm) below your eye. Press the sticker into place. Place a second sticker below your other eye. Look in a mirror to make sure both stickers are straight and level. Peel the stickers off when you’re done playing.
