So I started with painting the frame with a lilac/ pinkish color. This is the color the will show though the cracks.
Then when the paint is dry I go over the frame with the crackle glaze. This is going to dry for two hours.
After the two hours paint with another color. I took a white one. The paint has to be an water based acrylic. To remember is that the crackle will start right away so don´t go over the same area more than once if you can.
I´m really happy with the end result and here I just put in some pic I´ve on this board http://pinterest.com/juliakallen/petz/ .
