This is a photo of a nail I did about 2 years ago lol the photo is all odd looking but you get the idea I used
NFU.OH soft foil they have it in gold and silver it's not like a wrap or like the traditional nail foil/ glitzy lip transfer types this is more like gold leaf , thin and very delicate.
There is something else I use to do but no one wants my enhancements any more ( bloody Power polish lolol)
If you get some thicker foil like hair dressing foil or a magis wrap ,
you can then use a ball point pen to draw into it flowers , wavy lines , circles , patterns leafs look good , any thing ,
Then Turn the foil over so the indent is raised ,
Put it on your form
Do a clear or taransparent overlay ( maybe using color drops or NFU.OH jelly collection or even colored gel mixed in clear.
When cured remove foil and the pattern will be there , can do some amazing effects like this ,
A bit like before double glazed windows when the winter frost makes the patterns .
