Can I use standard polish and gems on top, boven of nail foils?

Hello Everyone,

I'm new to this forum so please don't tell me off if someone has already geplaatst this but from what i can see, no-one has.

Ive just started up a nail art business with my friend. Its small at the moment and we are still practicing our favourite designs and techniques.

I was just wondering about nail foil.

Is there anything else but the nail foil adhesive that makes it work?
Do we think eyelash glue may do the trick?
and also, once the nail foil is on,
can I apply polish designs on top, boven of it and gems?
of will that ruin the effect?
Please let me know your experiences and add pics if possible.
I love to see other people designs!

Thank u for reading!
