It's easier for you to use double eyelid stickers. You buy a thinner and longer one, clamp it with tweezers, look in the mirror and stick it in the corresponding position. You must buy it. Love likes it very much. You must put it in the right place. Don't be too far away from your eyelashes. Stick it at a distance of about 4 or 5 mm from the root of eyelashes, but it is just a double eyelid paste or glue. Wipe your eyelids before you do it!
