I recently was given this frame with a holy Cross in it because it was broken....
I thought it looked a bit shabby chic..... so I broke it up even more just to be sure. *wink*
It gives you immediate results which is much faster than the actual crackle finish you buy for big bucks at the hobby stores. After the paint is completely crackled on the frame---- I do take a brush full of watered down paint to fill in some of the larger crackled areas, but this is just a personal preference.
I also crackled the Cross and glued that to an old book page from 1852.
