So even though I think crackles are completely done, I had this weird feeling like I NEEDED to put crackle on top of my franken mani from last night... I know, black crackle over red has been done a million & a half times, but I don't know, it was calling to me haha.
here's one coat of Icing's black crackle [blanking on the name right now] over my nameless franken:
I like Icing's version because of the huge cracks it makes, it makes the base color show through a lot, which I like more than its counterparts.
