I keep my nails really short- for my feetsies it is a leftover habit from all those years of ballet. For my hands it is because I tend to nervously bite!
All decals seemed a bit much for my hands so I only put on a few, painting the other nails as sparkly as possible.
(ps the decals are kind of expensive,
around $10 a box,
but because my nails are short I can get two uses out of each box. )
