Step 3:Wait a beat (so the glue gets a little tacky), then lay the strip on the outer half of your upper lashline, positioning the seam as close to your lashline as possible. The trick is to drop the strip onto your lashes from above (don't come in from the front, perpendicular to your eye). The glue will do the rest—no need to press. Then, after running it through glue, drop the other half of the strip onto the inner half of your upper lashline. The two strips should overlap slightly at the middle of your lashline.
