It has been brought to my attention that Sephora by O.P.I has come out with a gold leaf top coat.
It's called 'It's Real 18K Gold Top Coat', and retails around $30-$36.
I made my own.
For this I used most of a bottle of Color Club clear polish (or top coat, whatever it is that comes in those 7 packs), two sheets of loose leaf gold, and about 3/4 a sheet of patent gold leaf. I believe these sheets are around 23.5 K or something like that (I was told something like that, the sheets have been in my family for a while (they belonged to my grandfather who gilded things).
The only thing is that since this is a higher grade of gold, it is more yellow than, say, 10K (which is probably one of my favourite gold percentages).
This was pretty easy to make, and definitely does not cost anywhere near the amount that the stores are asking for. :/
Have a wonderful day everyone!!! :D
