Here I only used a decal for an accent nail, and as my nails are a lot shorter I cut out what I needed and saved the rest for another manicure (I sure am frugal!). I always paint my nails with a base of white before applying decals. Let the base dry and then apply the decal over it for a lovely opaque look.
Above, side by side, amazing how one product used with different items or in a different way can give you a completely different look
I love water decals.
