I grew up in the 70's when false eyelashes were worn all the time....
1) practice putting them on several times as they aren't easy
2) look down into a mirror as you put them on
3) use tweezers to hold them as you can see what your doing more easily
4) clean all the glue off them before putting away
5) apply eyeliner (if using it) after the lashes
6) ask a mate to tell you if they think the lashes need trimming... most are properly trimmed but may be slightly to long for your eye shape and they will dig in as you blink
NEVER trim eyelashes while stuck on
7) use a blunted cocktail stick to carefully apply a tiny bit of glue to the ends if they havent stuck properly
8) practice lots again
Have fun sweetheart
