Some people just can't seem to colour inside the lines (*points to self; sighs*). Or keep cuticles clean when they paint their nails (am particularly hopeless re: painting right-hand nails -- #righthanded). Not a problem for a pro at say, Tips Nail Bar, or any other noted manicure bar or salon. But for regular folk, sometimes... 'nuff said.
Shaky-hand types could clean up polish-smeared cuticles with acetone and a Q-Tip (hands up if you've noticed how easy it is to go through 400 Q-Tips). Or you could go the preventative route with... craft glue? Well, why not? It dries clear, then peels off easily after you've finished your mani. Right?
Or you could keep cuticles clean with a pre-mani smear of Vaseline. Or rub oil around your nail bed, and swipe the nail with acetone before painting.
If you lack a steady polish hand, how do you ensure you colour inside the lines? How 'bout that glue idea?
