I've been playing with mdf atc's today, Decoart clear crackle paste and interference paints.
This is after they have completely dried and hopefully you can pick up the shimmer and the crackle.
And this is the other one. I only used two colours on this one.
Close up of the crackle.
To enhance the crackle, I covered each piece with white antiquing cream and wiped back.
Hopefully you can see the crackle much easier now.
I stamped over with black stazon using a script image.

All products are from the DecoArt media range.
